Re: [BackupPC-users] Full backups taking a very long time

[David Williams]

No, I don’t have a lot of small files.  As I mentioned, the full backups 
weren’t taking that long before the upgrade to Ubuntu 20.04.  Not sure why an 
OS upgrade would severely increase the time to back up.  The machine, hard 
drives (SSD’s) are all the same.

The version of BackupPC that comes with Ubuntu 20.04 is 3.3.2-3

I saw this happening when small files are backed up.

Unless there is a truly pathological number of small files (think tens
if not hundreds of millions), I don't think you can explain a 21 hour
backup period.

My Raspberry PI 4 on a home network backs up my Ubuntu 18.04 with
2.7GB and 321K files in under 12 minutes. And I think that is with
several simultaneous backups.

Re: [BackupPC-users] chroot failed

[David Williams]

Oli,

Thanks for the reply.  About 1 hour after I sent my email I realized that the 
issue was not with sudo, but with SSH and as you state below, the key.  Once I 
realized this I was able to get the login working without the password :)

Now, I am seeing if I have everything else configured correctly and trying to 
do a full back up.  Fingers crossed.

Dear David

Sorry for the late answer. I was quite busy. I try to write down the steps I 
did:

- In OS X System Preferences choose Sharing and  make sure you enabled remote 
login (I am pretty sure you already did this)

- I assume that you have a user backuppc on your host client. Make sure, that 
the user backuppc is able to log in by ssh without a pw. Otherwise it would not 
run.
(http://backuppc.sourceforge.net/faq/ssh.html)

- In OS X System Preferences choose Security and then the tab Privacy and  make 
sure that sshd and sshd-keygen-wrapper have full access to the hard disc. I use 
rsync only for my home folder. So eventuelly you have to add rsync to if you 
want to backup other system directories

- For rsync I installer homebrew (brew.sh). With this you can install a native 
rsync version with brew install rsync. I am not sure of backuppc works with the 
OS's native rsync.

- The images show my settings in the web frontend of backuppc








I hope this helps. But I am sure that the problem is that the user backuppc 
cannot login to your machine without a key.

Best regards
Oli

So, I really need some help on this.  I am trying to set it up with rsync now 
instead of samba, but I am having issues.  I’ve gone through a couple of 
articles I found on the interweb but not quite there.

I have upgraded my Mac to rsync version 3.1.3, which I read you have to be on 
rsync 3.x.  I created a rsyncd.conf and I have put my 2 shares that I want to 
back up from my Mac in this file.
I also went through the ssh set up and created keys and swapped them with the 
client and server.

I also put my username in the sudoers file on my Mac.  I set it to NOPASSWD and 
also set it so that it can only use the rsync command.  So this is what I have 
in sudoers file:
dwilliams   ALL = (ALL) NOPASSWD: /usr/local/bin/rsync

When I try and test this out with the following command it is always prompting 
me for the password and I have no idea why.  Entering the password does provide 
the correct information.
ssh -l dwilliams davesmac sudo /usr/local/bin/rsync --version

I thought the line I had put in the sudoers file would ensure it would not 
prompt for a password.  What am I doing wrong and how can I get this working so 
that I can start backing up my Mac again?
Any help would be much appreciated.

[BackupPC-users] Buying larger drive

[David Williams]

Quick question.  I currently have a 1TB hard drive that I use to back up 2 
computers and although this has worked ok for quite a while I need more space 
so I have ordered a 2TB drive.  I know I can clone the current 1TB drive to the 
new 2TB drive but is it also possible to just mount the new drive to 
/var/lib/backuppc and create the necessary directories with the correct 
ownership and permissions for backuppc to start backing up my 2 computers?  The 
configuration files are in /etc/backuppc so I am hoping that just mounting the 
new drive, creating the directories is all I need to do.  Obviously the 
pervious backups won’t be on the new drive this way and backuppc will 
(hopefully) start again anew.

[BackupPC-users] Issues with sendmail

[David Williams]

All,

I have recently installed ssmpt as it was needed to send emails through my smtp 
provider.  This works just fine but I noticed that BackupPC has stopped sending 
email.  I went through the following link 
(https://wiki.archlinux.org/index.php/SSMTP#Security) but still no joy.

When I try to use the following I get the error on the last line.
$ /usr/share/backuppc/bin/BackupPC_sendEmail -u 
dwilli...@dtw-consulting.com
Sending test email using /usr/sbin/sendmail -t -f BackupPC
sendmail: 550 5.7.60 SMTP; Client does not have permissions to send as this 
sender


However, still as backuppc, if I do the following it works just fine and I got 
an email.  So, seems to me that the user backuppc does have permission.
echo "Test: Sendmail" | sendmail -v 
dwilli...@dtw-consulting.com

Any ideas on how I can further troubleshoot this?

Re: [BackupPC-users] Backing up a Mac client - Help needed

[David Williams]

I believe I may have found the answer to this. Isn’t that always the case!!

Would I be correct in that the uid and gid parameters in the rsyncd.conf file 
would be the way to ensure which user and group the rsyncd process runs at?  
So, in the case below, I would ensure that the uid = dwilliams??

CGI didn't have permission to the file, once I gave CGI the appropriate 
permission the two graphs showed up.  Prior to that I just got 
placeholder icons, no images.

Any other ideas on why the graphs aren't showing?  It's been several 
days now that I have had backuppc running and the graphs are just 
showing as blank icons.
If I run the above rrdtool as above this is working fine and I can now 
see a graph with some blue bars to the right hand side.  No idea why it 
is not showing on the main backuppc page.

[BackupPC-users] New install - new issues

[David Williams]

Hi there,

I recently had to install a newer version of Linux (Kubuntu 15.10) and 
thus had to reinstall Backuppc (v3.3.0), which I did from repository.  I 
had several files already backed (config files) so I restored them.


Right now I am having a couple of issues that I'd be grateful of any 
help, advice, direction, etc.


I believe this is more of a samba issue but thought enough people on 
here would be able to provide help.  When I try to backup a windows 
laptop it fails and the error files shows the following:


cli_list: Error: unable to parse name from info level 260

When I use the smbclient command I can log into the windows machine no 
problems, but if I try and perform even a dir or ls command I get the 
above.  I have never seen this error before so not really sure what is 
going on. I'm going to continue digging around to see what I can find on 
this error but I am hoping that someone else has seen this error before 
and knows how to resolve it.

My Samba version is 4.1.17
This is a minor issue but it appears that there are a couple of images 
not displaying directly after the Failures that need attention area.  
When I right click on the image holder and select view image I get the 
following:



The image http://192.168.15.2/backuppc/index.cgi?image=4 cannot be 
displayed because it contains errors.

[BackupPC-users] Issues with Include and Exclude for a SMB backup

[David Williams]

  
  
Hi,

I am trying to ensure that I only back up certain directories on my
laptop, which is done via SMB. However, the include and exclude
just don't appear to be working at all.

For the sake of discussion let's say that the SMB share is
MyLaptop/Users. Underneath Users on this laptop I have the
following directories: Default, dwilliams and Public.
My Includes and Excludes are as follows:


When a backup finishes everything in the excludes section is getting
backed up, and several items from the include are not getting backed
up.

Any help would be much appreciated as there are a couple of
important directories under dwilliams that I want to ensure get
backed up.

Re: [BackupPC-users] Issues with Include and Exclude for a SMB backup

[David Williams]

  
  
Ok, so I removed the BackupFilesExclude
  and still it is backing up directories that are not in the
  include list, and also not backing up some directories
  that are in the include list! Obviously I am doing something
  wrong, but not sure what!

Per http://backuppc.sourceforge.net/faq/BackupPC.html#_conf_backupfilesexclude_
"For Smb, only one of $Conf{BackupFilesExclude} and
$Conf{BackupFilesOnly} can be specified per share."   The smbtar
client just doesn't have a way to handle both.   You'll either have to
arrange top level shares for the things you want to include or install
cygwin rsync on the PC so you can use the full syntax.

basically, you replace the ssh part with a corresponding sudo part. You also
need to remove one level of quoting. And set up sudo.

For example, the default RsyncClientRestoreCmd is (or was at some point)

$sshPath -q -x -l root $host $rsyncPath $argList+

which would become

/usr/bin/sudo $rsyncPath $argList

(note the missing + behind $argList). Replace RsyncClientCmd accordingly if
you also want to continue doing backups (without ssh).

You need an entry something like

backuppcALL=NOPASSWD: /usr/bin/rsync --server *

in /etc/sudoers (use 'visudo' to edit that).

The same principal is also applicable to tar backups.


[...]

Ah sorry for confusing the issue. I forgot that you can do direct
restores via the web interface. I run with that feature disabled for

So do I. For that case, you'd want to additionally enforce the --sender
command line option in the sudoers entry:

backuppcALL=NOPASSWD: /usr/bin/rsync --server --sender *

or even

backuppcALL=NOPASSWD: /usr/bin/rsync --server --sender 
--numeric-ids --perms --owner --group -D --links --times --block-size=2048 
--recursive *

(adapt to the command actually run by BackupPC - possibly consult your
auth.log to see the command actually passed to sudo).


As Les followed up with, my method bypasses the web interface totally.

Yes, but you *can* use sudo instead of ssh for escalating privileges on local
backups, and it does make sense, because you avoid the overhead of encryption.
In fact, for security reasons I use an 'ssh -l backuppc remote_host sudo rsync'
type of setup even for remote backups rather than allowing passwordless root
access with an unencrypted ssh key. Thus sudo is also a *more secure* option
for local backups. Someone should really put that into the wiki if it's not
already there ;-) (yes, I promise to really *try* to remember to do so ...).

Hope that helps someone :-).

Holger

Re: [BackupPC-users] Issues with backing up Windows laptop with SMB

[David Williams]

Got this working too, but some other issues now which I need to look 
into.  For some reason certain directories under my C:/users/dwilliams 
folder are not getting backed up.  Not sure why that would be but will 
try and take a look at this and see what I can find out.  However, 
backups are working now so that's great :)


Thanks for the help.

Running: /usr/bin/smbclient dwlaptop\\Documents -U dwilliams -E -N

You're supplying a '-N' switch to smbclient, thus requesting it not to pass a
password, and that's exactly what it's doing.

The behaviour changed some versions ago. Remove the '-N'.

(adapt to the command actually run by BackupPC - possibly consult your
auth.log to see the command actually passed to sudo).


As Les followed up with, my method bypasses the web interface totally.

Yes, but you *can* use sudo instead of ssh for escalating privileges on local
backups, and it does make sense, because you avoid the overhead of encryption.
In fact, for security reasons I use an 'ssh -l backuppc remote_host sudo rsync'
type of setup even for remote backups rather than allowing passwordless root
access with an unencrypted ssh key. Thus sudo is also a *more secure* option
for local backups. Someone should really put that into the wiki if it's not
already there ;-) (yes, I promise to really *try* to remember to do so ...).

Hope that helps someone :-).

Holger

Thank you for the quick response :) My config files are from several

out of date.  Will remove the -N as instructed and give it another try.

You're supplying a '-N' switch to smbclient, thus requesting it not to pass a
password, and that's exactly what it's doing.

The behaviour changed some versions ago. Remove the '-N'.

 Sure - you need exactly the same for a restore as a backup - that is,
 root access to the target from the backuppc account on the server.
 Depending on the platform, you may be able to (starting from root on
 the backuppc server:
 su - backuppc   (you might need 'su -s /bin/bash - backuppc' if there
 is no login shell for the account).
 ssh-copy-id root@target_host
 (and then answer the prompts to accept the host key and  for the
 remote root password)
 That uses a password-based connection to set the keys up for you for
 subsequent passwordless connections.

Ok, gave the above a try and this is what happened:

-bash-4.2$ ssh-copy-id root@linuxpc
/usr/bin/ssh-copy-id: ERROR: No identities found

That looks like you haven't set up the ssh key for backuppc to execute

to download through a browser and then copy it where you want.

 Then why bother with ssh at all?

 sudo -u backuppc  .../BackupPC_tarCreate -h linuxpc -n 612 \

 should do the trick I would think.
Ok, so what would go into the restore command then?  Would I just 
replace the restore command with the whole line above?  I am thinking 
not as it wouldn't be dynamic since it has the directory names in 
there.  I have no issues of skipping SSH just as long as I know what I 
need to put into the restore command in the config file.  Sorry, as 
mentioned in my original email I don't know that much about Backuppc.

Localhost that is set up to use sudo.  The backup runs through /var and

 You may need to have perl-suid (or perl-suidperl, depending on your
 linux distro and packaging) installed.  Or maybe httpd-suexec for some
 versions...

 And you don't see much in the web interface until you can log in as
 and admin user - so apache has to be configured to request a login for
 the location and you need to have your login in $Conf{CgiAdminUsers}.

Ok, so that is where I am stuck, apache is not asking me for a login.  I 
have my config.pl file from my previous install (located in

 Do you have a copy of your old httpd.conf file (and snippets from
 /etc/httpd/conf.d/ if you used them.   The authentication needs to be
 required when accessing the cgi script which might not be in the
 protected directory.

 If you are starting over from scratch, you might find it easier to use
 a version packaged for your linux distribution, although you have to
 pay some attention to where the packages move things and mount your
 old archive in the right place, it would make a future reinstall a lot
 easier.
I was able to get it working :)  I went from Mandriva Linux to Mageia, 
which is a fork of Mandriva, so very, very similar.  Thanks for all the 
help.

[BackupPC-users] Had to reinstall

[David Williams]

  
  
I had a hard disc crash which basically messed up my /usr
partition. So, I had to basically re-install Linux. This is just a
home box but I have had BackupPC running on it for quite a while
(years) and to be honest it just worked :) So, I reinstalled Linux
and I downloaded the backuppc package. I have gotten to the point
whereby I can get the webpage up but a few things are happening
different from my previous install.

1). The web interface is not showing any hosts but the overall
status does show that my disc 92% full. Best I can tell (remember)
I have 2 places for a hosts file. One in /etc/backuppc and the
other is where my TOP_DIR is set, which is /var/lib/backuppc. Both
have valid host files so I am really at a loss as to why the web
interface is not showing any hosts at all.

2). The web interface is not asking for my login/password but that
could be because I have not done something...very possible.

Would appreciate any help.

Thanks.

smbfs did not work and I got the following message: "smbfs is

Perhaps this is a windows 7 security issue, not sure. I know
several years ago I was using SMB to backup an XP machine and
didn't have these issues.
I'm not familiar with rsync so would have to look into that.

David,

Being a "mobile warrior," I
believe you would be best fitted with using rsync (cwRsync
for Windows)instead of smb. You also need to keep in mind that your system will need
to transfer all files across the pipe to check their
checksum. If you are connected via wireless when you are
home, I would not suggest it, unless your drive is
practically unused.

With that said, if you still would
prefer to use smb, I would suggest doing some basic
troubleshooting from another PC (if possible) by simply
connecting to the \\laptop1 device (you will
want to connect to the c$ share). If you can connect
successfully or if you don't have another device to test, I
would suggest running the following command on your linux
box:

smbclient -L ComputerName -U
Administrator*

If the system comes back with your
open network shares, then good. If it does not, then
something is wrong and you'll need to look into the error
message it gives back. If it does work, you can try one
last thing, actually mounting the drive to your server to
ensure that works.

1. Create a folder in /mnt using
mkdir /mnt/test
2. Run this command: mount -t cifs
//IP.AddressOrHostName.Of.Computer/c$ /mnt/test/ -o
username=Administrator*
3. If that does not work, exchange
cifs for smbfs. mount -t cifs
//IP.AddressOrHostName.Of.Computer/c$ /mnt/test/ -o
username=Administrator*

You should be able to cd to
/mnt/test and do a ls -aL to see all the data in the root of
your C: on your laptop. If that works, it *should* work

All,

I have now gotten to the point whereby the backup is at least starting.  
It is also stopping very quickly with the following errors:


full backup started for share \\laptop1
Xfer PIDs are now 28877,28876
Exec failed for
tarExtract: Done: 0 errors, 0 filesExist, 0 sizeExist, 0 sizeExistComp, 0 
filesTotal, 0 sizeTotal
Got fatal error during xfer (No files dumped for share \\laptop1)
Backup aborted (No files dumped for share \\laptop1)
Not saving this as a partial backup since it has fewer files than the prior one 
(got 0 and 0 files versus 0)

I suspect that I don't have some of the smb parameters setup correctly.  
I have done the following:


XferMethod = smb
SmbShareName = \\laptop1  (have also tried C$)
SmbShareUserName and SmbSharePasswd have both been set.
BackupFilesOnly = \users\dwilliams

How can I troubleshoot this issue further?  Are there any command line 
commands that I can use to ensure I can connect to laptop1 via smb?  I 
have Windows7 64-bit on the laptop.


Any additional help will be much appreciated.

Re: [BackupPC-users] One more time

[David Williams]

  
  
Ryan,
  
  Thanks for the info. Tried what you suggested and here is what
  happened.
  
  smbclient -L laptop1 -U dwilliams
  Enter dwilliams's password:
  session setup failed: SUCCESS - 0
  
  mount -t cifs //192.168.15.50/c$ /mnt/test/ -o username=dwilliams
  Password:
  mount error(13): Permission denied
  
  dwilliams is setup as an admin user on laptop1.
  
  smbfs did not work and I got the following message: "smbfs is
  deprecated and will be removed from the 2.6.27 kernel. Please
  migrate to cifs"
  
  Perhaps this is a windows 7 security issue, not sure. I know
  several years ago I was using SMB to backup an XP machine and
  didn't have these issues.
  I'm not familiar with rsync so would have to look into that.

  David,
  
  Being a "mobile warrior," I believe
  you would be best fitted with using rsync (cwRsync for
  Windows)instead of smb. You
  also need to keep in mind that your system will need to
  transfer all files across the pipe to check their checksum.
  If you are connected via wireless when you are home, I would
  not suggest it, unless your drive is practically unused.
  
  With that said, if you still would
  prefer to use smb, I would suggest doing some basic
  troubleshooting from another PC (if possible) by simply
  connecting to the \\laptop1 device (you will
  want to connect to the c$ share). If you can connect
  successfully or if you don't have another device to test, I
  would suggest running the following command on your linux box:
  
  smbclient -L ComputerName -U
  Administrator*
  
  If the system comes back with your
  open network shares, then good. If it does not, then
  something is wrong and you'll need to look into the error
  message it gives back. If it does work, you can try one last
  thing, actually mounting the drive to your server to ensure
  that works.
  
  1. Create a folder in /mnt using
  mkdir /mnt/test
  2. Run this command: mount -t cifs
  //IP.AddressOrHostName.Of.Computer/c$ /mnt/test/ -o
  username=Administrator*
  3. If that does not work, exchange
  cifs for smbfs. mount -t cifs
  //IP.AddressOrHostName.Of.Computer/c$ /mnt/test/ -o
  username=Administrator*
  
  You should be able to cd to
  /mnt/test and do a ls -aL to see all the data in the root of
  your C: on your laptop. If that works, it *should* work
  assuming your credentials are correct in BackupPC's configs.
  
  P.S. Once you test mounting, you'll
  probablywant to unmount with umount /mnt/test

Is there any hope you can get a static IP address assignment for your
laptop, so that the BackupPC server doesn't have to 'hunt' for it?

This is what we do everywhere, and it solves the problem perfectly.

Yes, all DHCP servers should have a way to reserve an IP by MAC address,
and most will give the same MAC the same IP for some reasonable length
of time anyway unless there is a big turnover with the lease expired.
*Anyway, if you just connect to the backuppc web interface from the
laptop itself and request the backup, it will find you - and keep
working at least until the IP changes.*

I do connect to the web interface from the laptop itself and request the 
backup and I get the following message:


laptop1 is a DHCP host, and I don't know its IP address. I checked the 
netbios name of 192.168.15.155, and found that that machine is not laptop1.


Until I see laptop1 at a particular DHCP address, you can only start 
this request from the client machine itself.


That's my issue, but will look into trying to reserve a specific address 
for this laptop as that's probably an easier solution to the problem, at 
least for me :)

Hi David

I have a ReadyNAS Duo [X-RAID] with two 1TB disks in raid 0 (mirrored). I
believe it's close to what you are looking at. It's mounted as NFS in my
Ubuntu server. I use this set-up in my home for personal as well as business
use. It has worked flawlessly since I installed it, I think it was in
october last year. I backup several clients to it as well as the Ubuntu
server it self. A full backup typically reaches a speed of 8 MB/s, but I
haven't made any effort to tune the setup, I just plug and pray ;-) . I also
store some larger files on it and I stream video from it as well. Works
great.

What do you want to know?

Regards
/Erik

I currently have a Western Digitial 1TB My Book World device which seems
like it’s starting to play up, which is a shame because I’ve hacked it (it’s
basically a Linux server) so that I could mount the drive as NFS under Linux
and perform backups using Backuppc.  I haven’t look into the problem with
the drive too much, but after a few days of it being mounted I can’t cd into
the mount partition of the drive  L

 

I’m looking to get a replacement which will mainly be used to backup various
mount points on my home Linux server.  I haven’t done too much research yet
but need something that is one the cheap side, is compatible with Linux and
preferably will let me format the drives to ext3 too, or at least mount the
drives such that I can perform backups using Backuppc, which requires
hardlinks.

 

I took a very quick look around and saw the Netgear RND2210-100NAS which
looks pretty decent (states that it’s compatible with Linux) and has 2
drives.  Looks like it already comes with 2 x 1TB drives (no idea what type
of drives though if it does indeed come with 2 HDs) and this would be great
as I could use 1 on the 1TB drive for my backups and the other to hold my
photos, music and videos, which would free up some space on my Linux server.

 

Has anyone ever used (or is currently using) the above Netgear device and
could provide feedback?

 

If I can’t find a decent NAS then I’ll have to buy several HD’s and
re-config my Linux server with much larger drives.

 You probably want to configure the WINS server in smb.conf so it is the

 in the command line.  You should also set $Conf{DHCPAddressRanges} in

 backuppc so it will know where to probe for dhcp-assigned addresses.

Re: [BackupPC-users] Communicating with a windows laptop on my workgroup

[David Williams]

Chris,

 

Thanks for the additional help on this.  I was able to make the changes and
set my laptop to look at my Linux box as a WINS server.  So now when I
perform the following command from the command line I get the following:

 

nmblookup -U 192.168.15.2 -R laptop1

querying laptop1 on 192.168.15.2

192.168.15.155 laptop100

 

That to me means it works and it's finding the IP address for my laptop :)

 

However, there are still issues.  When I try and perform a backup of laptop1
from within the web interface I get the following message:

 

Error: Can't find IP address for laptop1

 

laptop1 is a DHCP host, and I don't know its IP address. I checked the
netbios name of 192.168.15.155, and found that that machine is not laptop1.

 

Until I see laptop1 at a particular DHCP address, you can only start this
request from the client machine itself.

 

The strange thing is, I was on the client machine at the time and trying to
back it up manually from the web interface!

 

I also updated the config file for laptop1 such that NmbLookupFindHostCmd is
set to:

 

$nmbLookupPath -R -U 192.168.15.2 $host

 

Feel like I am getting closer to getting this working now that I can at
least get success from the nmblookup command.

Subject: Re: [BackupPC-users] Communicating with a windows laptop on my

Hi there,

 

 No, it doesn't make sense.  What you want (and need) is a master

 browser, which (on a workgroup, not a Windows domain) is elected

 from computers on the segment.  N.B.:  if you're not on the same

 segment and don't have a domain controller, you can't browse or use

 nmblookup.

 

WINS was created to work around this, and may help you in this case as

well.

 

Name resolution in SMB/AD uses three methods:

  - broadcast

  - WINS

  - DNS

 

The thread has mostly been about getting a master browser working, but

if the two BackupPC  client nodes are on the same segement, broadcast

resolution should work.  The exception might be if your client is not

responding to Netbios broadcast name queries (UDP 137).

 

So WINS can provide you a central name resolution service (WINS

server) which can respond to name queries on behalf of clients.  The

caveat being the clients need to know to register their name with a

WINS server.  WINS also solves the name resolution between segments

problem.

 

DHCP can dish out the WINS server setting (ISC dhcp name it

'netbios-name-servers'), but since you're statically allocating an IP

address, you'll need to manually configure the setting.  I found

http://publib.boulder.ibm.com/infocenter/iseries/v5r4/topic/rzahl/rzahlcfgpc
winsxp.htm

which describes how to do it for Windows XP.

 

The samba server requires the option

  wins support = yes

 

Now when you're client boots up, it'll register it's name with the

WINS server.

 

nbmlookup accepts a -R and -U option.  From the manpage:

  -U unicast address

 Do a unicast query to the specified address or host unicast

 address. This option (along with the -R option) is needed to

 query a WINS server.

 

  -R

 Set the recursion desired bit in the packet to do a recursive

 lookup. This is used when sending a name query to a machine

 running a WINS server and the user wishes to query the names in

 the WINS server. If this bit is unset the normal (broadcast

 responding) NetBIOS processing code on a machine is used instead.

 See RFC1001, RFC1002 for details.

 

Test first to ensure nmblookup returns the expected result, and then

update backuppc to use the above options when calling nmblookup.

 

The third resolution method (DNS) is just that: given a bareware name,

append a suffix to the name and send a query to the configured DNS

server.  AD uses this now to replace broadcast and WINS resolution,

coupled with dynamic DNS for clients to register their name to the DNS

server.

 

So hopefully that can help you to configure things the way you'd like

to - personally, the neatest solution is to setup a DNS server, and

configure your a DNS record for your desktop since it's statically

assigned, but all methods above should work they way their advertised

to work :)

 

Regards,

 

Chris Bennett

Subject: Re: [BackupPC-users] Communicating with a windows laptop on my
workgroup

 

 I posted this to a Linux forum but also wanted to post it here since this

 is also relates to backuppc.

 

Only peripherally, in the sense that if you're using smb and smb doesn't

work, backuppc won't work.

 

 I did post something a while back and some mentioned about modifying

 Samba so that it became a local master.  Anyway, I

 made the changes to my smb.conf file with the following:

 

 local master = yes

 preferred master = yes

 wins support = yes

 

 That said, I still cannot seem to perform a nmblookup on a windows laptop

 that is connected to my network that has a dynamic IP address L

 

I'm not entirely sure why you'd want to use NMB rather than DNS; then

again, I don't recommend SMB since rsync is available.

 

I am by no means an expert in this area at all, and I am open to looking at
other options.  I know that I had the smb method working a while back on a
fixed IP address windows machine.  The last time I posted on here with this
issue, albeit with less information, I was asked to make the changes to
Samba that I indicated above.  I don't pretend to always understand the ins
and outs, just as long as I can get it working J

 

 I have just noticed something in my syslog, which I believe is related to

 a change in my Samba setup.  I am using Backuppc to perform backups on my

 linux server and I was (and still am) having a problem in that I wasn't

 able to back up any machine that had a dynamic IP address, namely my

 laptop.

 

Does it actually resolve via DNS?

 

This is a home network so to be honest, I wouldn't even know how to go about
testing this.  My laptop is associate to a Workgroup and my Linux server has
a static IP address within the 192.168.15.x range.  I can ping the laptop by
ip address but I am not sure what it's normal address would be.  For
example, would it be laptop1.workgroup.com ?

 

 It

 seems that nmblookup will not resolve the ip address from any machines on

 my

 network.  Really not sure what the problem is since I have very little

 experience with this.  Also, I don't remember what change I made to the

 samba configuration (I had a look but nothing jumped out) other than it

 had to do with enforcing Samba to act as a Domain Master if that makes

 sense.

 

No, it doesn't make sense.  What you want (and need) is a master browser,

which (on a workgroup, not a Windows domain) is elected from computers on

the segment.  N.B.:  if you're not on the same segment and don't have a

domain controller, you can't browse or use nmblookup.

 

 The errors I am getting in my syslog are as follows:

 nmbd[4123]:   find_domain_master_name_query_fail:

 nmbd[4123]:   Unable to find the Domain Master Browser name XX1b for

 the workgroup X.

 nmbd[4123]:   Unable to sync browse lists in this workgroup.

 

That's normal.  The local master browser is looking for a domain master

browser.  Which you apparently don't have.  This is indicating that for

whatever reason, samba is not functioning as the LMB.  There may be better

clues when it starts up, since typically that's when the elections are

held.

 

In your log.nmbd, you should see this sort of thing:

 

become_domain_master_browser_bcast:

  Attempting to become domain master browser on workgroup X on subnet

10.168.0.1

 

If you're not seeing this, then something's funny with your smb.conf.

 

After a restart to Samba here's what's in my log:

 

[2010/03/18 13:06:58,  0]
nmbd/nmbd_become_lmb.c:395(become_local_master_stage2)

  *

 

  Samba name server LINUXPC is now a local master browser for workgroup
WORKGROUP on subnet 192.168.15.2

 

  *

[2010/03/18 13:06:58,  0]
nmbd/nmbd_browsesync.c:350(find_domain_master_name_query_fail)

  find_domain_master_name_query_fail:

  Unable to find the Domain Master Browser name WORKGROUP1b for the
workgroup WORKGROUP.

  Unable to sync browse lists in this workgroup.

 

 

 I'd really appreciate any help that would allow me to be able to use

 nmblookup (which is what backuppc uses to resolve client names to an IP

 address) and work out just what I did to samba.

 

Can you actually browse any windows shares at all?

Subject: Re: [BackupPC-users] Communicating with a windows laptop on my

 I posted this to a Linux forum but also wanted to post it here since this

 is also relates to backuppc.

 

Only peripherally, in the sense that if you're using smb and smb doesn't

work, backuppc won't work.

 

 I did post something a while back and some mentioned about modifying

 Samba so that it became a local master.  Anyway, I

 made the changes to my smb.conf file with the following:

 

 local master = yes

 preferred master = yes

 wins support = yes

 

 That said, I still cannot seem to perform a nmblookup on a windows laptop

 that is connected to my network that has a dynamic IP address L

 

I'm not entirely sure why you'd want to use NMB rather than DNS; then

again, I don't recommend SMB since rsync is available.

 

I am by no means an expert in this area at all, and I am open to looking at
other options.  I know that I had the smb method working a while back on a
fixed IP address windows machine.  The last time I posted on here with this
issue, albeit with less information, I was asked to make the changes to
Samba that I indicated above.  I don't pretend to always understand the ins
and outs, just as long as I can get it working J

 

 I have just noticed something in my syslog, which I believe is related to

 a change in my Samba setup.  I am using Backuppc to perform backups on my

 linux server and I was (and still am) having a problem in that I wasn't

 able to back up any machine that had a dynamic IP address, namely my

 laptop.

 

Does it actually resolve via DNS?

 

This is a home network so to be honest, I wouldn't even know how to go about
testing this.  My laptop is associate to a Workgroup and my Linux server has
a static IP address within the 192.168.15.x range.  I can ping the laptop by
ip address but I am not sure what it's normal address would be.  For
example, would it be laptop1.workgroup.com ?

 

 It

 seems that nmblookup will not resolve the ip address from any machines on

 my

 network.  Really not sure what the problem is since I have very little

 experience with this.  Also, I don't remember what change I made to the

 samba configuration (I had a look but nothing jumped out) other than it

 had to do with enforcing Samba to act as a Domain Master if that makes

 sense.

 

No, it doesn't make sense.  What you want (and need) is a master browser,

which (on a workgroup, not a Windows domain) is elected from computers on

the segment.  N.B.:  if you're not on the same segment and don't have a

domain controller, you can't browse or use nmblookup.

 

 The errors I am getting in my syslog are as follows:

 nmbd[4123]:   find_domain_master_name_query_fail:

 nmbd[4123]:   Unable to find the Domain Master Browser name XX1b for

 the workgroup X.

 nmbd[4123]:   Unable to sync browse lists in this workgroup.

 

That's normal.  The local master browser is looking for a domain master

browser.  Which you apparently don't have.  This is indicating that for

whatever reason, samba is not functioning as the LMB.  There may be better

clues when it starts up, since typically that's when the elections are

held.

 

In your log.nmbd, you should see this sort of thing:

 

become_domain_master_browser_bcast:

  Attempting to become domain master browser on workgroup X on subnet

10.168.0.1

 

If you're not seeing this, then something's funny with your smb.conf.

 

After a restart to Samba here's what's in my log:

 

[2010/03/18 13:06:58,  0]
nmbd/nmbd_become_lmb.c:395(become_local_master_stage2)

  *

 

  Samba name server LINUXPC is now a local master browser for workgroup
WORKGROUP on subnet 192.168.15.2

 

  *

[2010/03/18 13:06:58,  0]
nmbd/nmbd_browsesync.c:350(find_domain_master_name_query_fail)

  find_domain_master_name_query_fail:

  Unable to find the Domain Master Browser name WORKGROUP1b for the
workgroup WORKGROUP.

  Unable to sync browse lists in this workgroup.

 

 

 I'd really appreciate any help that would allow me to be able to use

 nmblookup (which is what backuppc uses to resolve client names to an IP

 address) and work out just what I did to samba.

 

Can you actually browse any windows shares at all?

 Probably not.  Somewhere on your network you've got a DHCP server that's

 giving your laptop an IP address, and there's probably a DNS server that's

 either being updated directly by your laptop (Windows does that) or by

 your DHCP server.

 

 At any rate, to find out, open a command window on your Windows box and
type:

 

 ipconfig

 

 Which should yield a connection-specific DNS suffix.

 

 Workgroups/WINS is -quite- different, and entirely unrelated.

 

For a network with only a few machines, the easiest approach might be to 

configure the router/dhcp server to give out fixed IP addresses based on the


known ethernet MAC addresses.   Most home routers have a simple web
interface 

and the ability to configure this.  They may also offer to provide DNS, but
for 

a couple of machines it doesn't matter - you can just set dhcp to 0 in
backuppc 

and put the IP address in ClientAlias.

 

That's a good idea. I'll check that out as it would be much simpler.  I'll
only ever have 3-4 laptops that I'll want to consider backing up.

[BackupPC-users] Backing up a laptop via DHCP

[David Williams]

I have a simple home network setup on the 192.168.15.x subnet.  To date I
have just been backing up items on the backup server itself and that has
been working fine.  The backuppc server has a static IP address.  I now want
to add a couple of laptops to the backup but according to backuppc it can
never locate these laptops.  I've gone through the documentation about
nmblookup using the -A or -B options but nothing seems to work :(  At a loss
as to how to proceed now.  The laptops will always be set to DHCP so I can't
locate them by IP address.

 

My home network is basically a windows Workgroup and I was planning on
access my laptops via smb.  From my backuppc server I can see both laptops
on the workgroup.

 

Any help, guidance would be much appreciated.

[BackupPC-users] Backup Taking Forever

[David Williams]

All,

 

I have had to reconfigure backuppc a little so that I can get it to work
with my external USB drive.  This mainly involved getting my external drive
mounted as NFS, and also mounting it to /var/lib/backuppc

 

Backuppc will start just fine and I can log into the web interface and see
my client (local machine)  and see the configuration settings, both the
global one and for the specific machine.

 

The specific machine configuration file is configured so that 'TarShareName'
contains:  /var, /etc, /photos, ..and several other partitions.  I also have
set the 'BackupFilesExclude' to: /var/lib/backuppc.

 

When I start a full backup I notice that the file NewFileList is creating
entries for /var/lib/backuppc/* which is confusing to me as I'd expect this
to be exclude since it is part of the exclusion path.

 

I am using tar as the XferMethod.

 

Am I missing something that would prevent the exclude from working ?

 

I am running backuppc on Mandriva 2009.0 and I have version 3.1.0-7.

Please post/send a copy of your configuration file in (sometimes)

Without seeing the whole config file, or at least the include/exclude,
share name sections, it will be very difficult to help, other than to
say You have an error with the configuration of one of those settings.

Chris,

 

I know that performance to an external USB drive isn't the greatest, but if
you re-read my original post you will see that my concern is that my
excluded items are appearing in the NewFileList file, which they shouldn't
be, at least not the way I understand it.

Let's get this straight here. You are backing up a machine on your network
to an external USB drive. I have noticed major issues myself when network
file transfer is combined with USB file transfer. It just takes forever.  I
recommend trying an eSATA solution if you want to use an external drive.

Re: [BackupPC-users] External WD Worldbook Device

[David Williams]

I did finally get around to hacking my drive and enabling NFS.  I can now
mount it as NFS and backuppc is now working again :)

However, there might still be something wrong with my setup.

I am running Mandriva 2009.0 and installed backuppc from the Mandriva
respostiory.

I updated the config.pl file and one of the things that I did change was the
TopDir parameter, which I set to /backups

My backups are currently going to /backups/pc/, where  is the host
that I am backing up.

I was re-reading the email below about the pool files and I didn't see
anything under /backups/cpool or /backups/pool.

On further investigation I do see files/directories under
/var/lib/backuppc/cpool.  By changing the TopDir parameter in the config.pl
file have I messed anything up ?  Backups seem to be working (very slowly),
but they are working.  I am assuming that this is ok but not sure.

Under /var/lib/backuppc/cpool are directories like 0/ 1/ 2/ 3/, etc but when
I drill down into some of these directories I don't see any files.

Would appreciate some help.

 Les,
 
 I believe that under the Mandriva package we are allowed to change the
 TopDir and it is in the config.pl file.

That's not likely. When you install from source, the configuration 
process modifies the code, embedding this location elsewhere.  If you 
don't re-run that process it won't be right.

 When I originally started Backuppc
 it was complaining that it could not create a hardlink under
 /backups/pc/ and /backups/cpool.  It wasn't looking at
 /var/lib/backuppc.  Even with version 3.0 I had TopDir set to /backups and
 backups were being created under /backups.

The test in 3.1 was added to catch this kind of mistake.

 Perhaps it has been 'failing', but I had valid backups that I have
restored
 from.  Whether it was wasting space I don't know, perhaps it was.  Also,
 even though I cannot currently do backups I can restore from existing
 backups and the restore is coming from /backups.  Based upon that I would
 say that the Mandriva package allows the change of the TopDir.

If pooling had ever worked you should have a large tree of files with 
long hash codes for names under the pool or cpool directory.  Does 'ls 
-lR' or 'find' show them?   Backups are stored under the appropriate pc 
directories in any case, but the pooling that eliminates duplicate 
copies can only work when the hardlinks succeed.  If you do have pooled 
files (and ls -l should show link counts  1), then there must be 
something different about the mount options on the new system.

Re: [BackupPC-users] External WD Worldbook Device

[David Williams]

If you installed from scratch from the sourceforge tarball you would be 
able to change the storage location, but the location is embedded in the 
code during the install process.  If you are using a version packaged 
for a distribution, this step has already been done and you can't change 
it with just the TopDir setting.  You really need to mount the disk at 
/var/lib/backuppc (copy everything that needs to be there first). You'll 
probably also need to mount the disk async to get any performance.

Les, thanks for the info.  Can you just give me a little more info in
regards to what you mean about copy everything that needs to be there
first.  If mount my drive from the current location (/backups) to
/var/lib/backuppc then won't everything that is currently in /backups be
where /var/lib/backuppc is now ?  Do you mean to copy whatever is currently
in /var/lib/backuppc to /backups first, and then mount the drive at
/var/lib/backuppc ?

I current mount the NFS drive as follows:

backupdevice1:/shares/internal/PUBLIC /backups nfs
rsize=8192,wsize=8192,nosuid,soft 0 0

I took a look at the options and there is no async option, just a sync
option.  According to the info sync does the following:  All I/O to the file
system should be done synchronously.

Re: [BackupPC-users] External WD Worldbook Device

[David Williams]

Just trying to follow up on this.

 

So, the workbook drive that I have cannot create hard links L so this means
I can no longer use this drive for doing backups, since the hardlink check
will stop this.  Is the hardlink issue related to the drive itself, or is it
related to the fact that it is formatted to NTFS format ?

 

Is there a way to format this drive so that it can create hardlinks (ext3?)
and can be used for backups again ?  It's a 1TB drive and I'd hate to have
to buy another drive.

but no one ever replied to my post.

In short yes, the hardlink test is a good thing, but to me it seems it gets
done too early. 

In the old 3.0.0 you could just format a usb drive as ext3 and plug it in on
the same mount point and backuppc would start, create pc, cpool, pool and
trash directories and carry on.
Now in 3.1.0 it does the hardlink check before creating any directories and
becuase the hardlink check is done on subdirectories it fails.

I would absolutely love it if the top level directories were still created
by backuppc first before doing the hardlink test. If those directories are
created because they dont exist and the hardlink test fails then just remove
the directories. Or leave them there, all you've done is create a few
directories.

Or how about just making some temp directories as part of the hardlink test
underneath the $Topdir? That would be the same as trying to create hard
links under TopDir/pc/ etc.

Re: [BackupPC-users] External WD Worldbook Device

[David Williams]

The drive is supposed to be a NAS drive, in that it is connected directly to
my router.  Hoping that someone else has this kind of drive and has come up
with a solution to this problem.  So far I have not been able to see how I
can reformat it :(  There is a web interface for the drive but even with
that there doesn't appear to be a way to re-format the thing.  Perhaps this
is not something that can be done, or that WD want people doing, which is
understandable.

I mount the drive as follows:

//192.168.15.6/public /backups cifs rw,
username=user,password=passwd,uid=backuppc,gid=backuppc 0 0

NTFS does support hardlinks. (But thats a now so well-known feature.) So
it might depend on how you mount the drive.

I'm not sure whether you can reformat it. If it's just USB-attached,
then yes, just go ahead. If it's some sort of NAS, it depends on the
device.

You could always create some huge container file and create an ext3
filesystem within that. Performance won't be great, but it'll work.

HTH,

Tino.

[BackupPC-users] External WD Worldbook Device

[David Williams]

All,

Up until very recently I have had BackupPC 3.0 working with my 1TB external
WD Mybook world edition device, which is connected to my LAN and which I
mount via cifs.  I recently had to upgrade my machine to a newer version on
Linux (Mandriva 2009.0) and with that comes BackupPC 3.1.

Once I had setup installed BackupPC 3.1, mounted my backup device using cifs
and restored my configuration files I started up BackupPC only to get the
message:

Can't create a test hardlink...

And BackupPC would not start :-(  Thankfully I have been able to comment out
this check from the BackupPC program and get BackupPC up and running so that
I can restore what I need from my backup drive via the web interface.

Under BackupPC 3.0 I never had a problem performing backups and I can still
access the backups that I have from the 3.0 version.  There are no error
messages in any of the log files.  So, did something change between 3.0 and
3.1 ?  Is there a way I can check manually by creating a hardlink on the
backups partition from the shell ?  Sorry, not a Linux guru so not well up
on the commands to do this.

I did take a look through the archives but nothing jumped out to me as to
the problem.  I would assume that since backups were working just fine with
3.0 that they should be fine in 3.1 and that my external drive is ok?

Would appreciate any help as I'd like to get my backups up and running
again.

I did do a df -i and got the following output:

FilesystemInodes   IUsed   IFree IUse% Mounted on
//192.168.15.6/public
116M1.7M115M2% /backups

Hi David,
Check your permissions on your backup folders. There is a chance that  
your new installation create your BackupPC user and group with a  
different numerical id than your previous install. If you do a ls -la  
on /backups and get a number back instead of a user/group name that is

Re: [BackupPC-users] External WD Worldbook Device

[David Williams]

I'm not sure what the filesystem is.  I suspect it is NTFS.  I guess
whatever these drives come as.

I did try what Tino suggested and this is what happened:

[r...@dtwconsulting backups]# echo hello  testfile
[r...@dtwconsulting backups]# ln testfile linkedfile
ln: creating hard link `linkedfile' = `testfile': No such file or directory

So yes, does look like there is a problem.

I have checked my previous backups and don't see any errors though, and I
was able to restore some of the files !

Is there a way that I can reformat this drive to ext3 ?  Is it even possible
to format the drive from linux when it is mounted as cifs ?

 I'm not sure whether CIFS supports hardlinks.

I believe CIFS does, but the underlying file system may not. What is  
the file system on the drive? It might be that hardlinks never worked  
and that the check was only added in 3.1.

Not directly since you use the drive as a NAS, therefore you access it
via some network protocol. Does it support NFS? If so, try using that
and perform the above test.

A not-so-nice solution would be to create an x GB file and format that
with whatever unix filesystem you like.

It would work roughly like this (for a 10 GB volume):

dd if=/dev/zero of=/backups/backuppc-volume bs=1M count=10240

mke2fs -m 1 -j /backups/backuppc-volume

mount -o loop,noatima,nodiratime /backups/backuppc-volume /var/lib/backuppc

If you run out of space on the volume later, you may resize it by
growing the file first (be careful!), then resizing the file system.

I suppose, performance is not an issue for you - it may be pretty
slow...

I wonder how you managed to do backups the first time, though... you
only upgraded your server? Then there must have been a way to create
links or BackupPC would have complained a lot.

HTH,

Tino.

Re: [BackupPC-users] External WD Worldbook Device

[David Williams]

Les,

I believe that under the Mandriva package we are allowed to change the
TopDir and it is in the config.pl file.  When I originally started Backuppc
it was complaining that it could not create a hardlink under
/backups/pc/ and /backups/cpool.  It wasn't looking at
/var/lib/backuppc.  Even with version 3.0 I had TopDir set to /backups and
backups were being created under /backups.

Perhaps it has been 'failing', but I had valid backups that I have restored
from.  Whether it was wasting space I don't know, perhaps it was.  Also,
even though I cannot currently do backups I can restore from existing
backups and the restore is coming from /backups.  Based upon that I would
say that the Mandriva package allows the change of the TopDir.

You can't change the location in the config in pre-packaged versions. 
There have been about a million discussions on this list about that 
issue.  If you get the original package from sourceforge and install 
yourself, you have a chance to pick the location.  In the RPM and deb 
packaged versions included in distributions, someone has already made 
that choice and you can't change it.

  This has been working like this for a few years now.

Or failing... The older version just didn't test.  You'll end up with 
working backup copies but no pooling if the links don't work so it 
wastes a lot of space.

Re: [BackupPC-users] SMB, NAS and Backuppc

[David Williams (DTW Consulting)]

You should be able to use fstab to do this also. I did for a 1TB WD drive that sounds very similar and I had the same problem with permissions. Putting a line in fstab and using cifs with uid and gid = backuppc did the trick.In my case, this WD drive is painfully slow and only backs up at a rate of 2MB/sec and a full back up takes about 15 hours :( Not sure why this is so slow, maybe that's just what happens when backing up to a cifs mount? Don't know.The WD drive is formatted as a NTFS partition (if I remember correctly). Wish there was a way to format is a linux partition but I don't think there is.

First of the backupPC server is a vmdk running on ESX, though the fact that its ESX should not matter. The backupserver is on a private 192 network along with 3 clients using a 2nd interface. The NAS drive is a LaCie Big Ethernet Disk (1T

(CIFS to) The NAS drive is formatted as xfs and cannot be changed. To connect to the GUI I run a ssh tunnel.   I have mounted the NAS drive using the below cmd in fstab on the backupserver.//192.168.10.x/backuppc /mnt/net-storage   smbfs  rw,uid=105,umask=666,username=backuppc,password=backuppc,auto 00   The drive mounts perfectly. I have tried it with out the uid and umask and it works fine. (I added these in as a last effort).   The basic trouble is BackupPC cannot write to the NAS drive as user backup
 pc. You cannot run 'chown' any files on the NAS drive.   I have su'd to backuppc and ran the ./BackupPC_dump -v -f 192.168.10.x but receive a 'permission denied' error on creating the file structure on the NAS drive. Obviously you receive a similar error when you run a backup from the GUI I have also added backuppc to the sudo file and ran the above cmd as sudo. An error is produced informing that you must 'su backupppc' to run it. When you cd to the NAS drive you cannot create a file as user backuppc, unless you sudo backuppc first. As root you can create files on the NAS All the files on the NAS drive are owned by root.user and cannot be changed.   My research into this matter has not present many options.

Re: [BackupPC-users] SMB, NAS and Backuppc

[David Williams (DTW Consulting)]

I to am using my WD NAS as a cifs mount and backuppc seems to be backing up to it just fine. I don't see any errors on the host status page.When you say archive space, you mean the location that all the backups are stored right ? If that's what you mean, then that is what I am doing.

 Wow, that worked like a charm. One of three client servers are currently 
 backing up now, with no 'permission denied' errors. I am pretty excited 
 and  i can now move on to building a trixbox server.
 
 In retrospect the solution you suggested makes sense, my cmd line had 
 incorrect syntax. A fellow worker suggested i place the command in the 
 rc.local file. So the drive will mount upon reboot.
 

Are you trying to use a smb/cifs mounted filesystem as the archive space 
for backuppc?  I wouldn't expect that to work since backuppc needs to be 
able to make hard links to the pool area.  Be sure to check your log 
files for link errors.

Re: [BackupPC-users] Problems starting backuppc under Mandriva 2008

[David Williams]

Craig,

I took a look at XferLOG.bad.z file and I couldn't see any errors from tar
at all.  I'm assuming that the errors would be at the end of the file.  At
the time the error occurred it was backing up /music.  This mount point
contains 9351 files.  Would that cause a problem ?  Would it be better to
break out this mount point with different sub-directories ?

Regards,

David Williams

Somehow this file got trashed in this distro.

I am the only one with this issue then ?  Is this something I need to take
up with Mandriva ?

All,

 

I tried to go onto sourceforge and do a search but kept getting an error
message saying Unable to connect to Search Server.

 

I've had backuppc installed for quite a while and recently noticed that it
wasn't running.  When I went to start the service I got the following
messages:

 

./backuppc start

I've no idea what's going on.  Looks like backuppc was upgraded to 3.1.0
from the Mandriva sources a while go.  Not sure if this is a problem with
the Mandriva package or something else.  I've put a not on the Mandriva
forum too, but that might take a while before I get a response.  Worst case
is I will uninstall the package from Mandriva and install backuppc from
source.

 

Any help would be much appreciated J

Yes, that is probably it.  I don't think my files change that much.

Thanks for the speedy responses :)

 However, when I do a df it still shows that my backup drive is 91% full L
 I've some postings on this before and I thought that this removing of
 incremental and full backups would regain some space.

If your files aren't changing that much (and if they're just documents and
the like, they're probably changing less than you think in terms of size
bytewise); you might not have that much space used by your incrementals.

[BackupPC-users] Backup Speed

[David Williams]

All,

Just looking to see if my backup speeds are in the right range or if they are a 
little slow.

My setup is as follows:

1 Linux box running Mandriva 2006.  This is my backuppc server and I am backing 
up several partitions on this box. 
Total backup size is around 65GB for a full backup.  The incrementals are about 
the same size too, which surprises me.

1 Windows box running Win XP.  The Linux box is running samba and backsup the 
windows box via samba.  A full backup is
around 40GB with the incremental being around 3 GB.

The following is what is being reported as the MB/sec

Windows: around 5 MB/s
Linux:   Between 9.5 to 10.8 MB/s

Both these boxes are on the same LAN and are both directly connected to my 
router.  The Ethernet cards are 10/100.  I
would have hoped for a faster throughput but perhaps there is a good reason for 
this?  At least on the Linux box
(since there should be no network overhead) I'm very surprised by the speed.  
The linux box is being backed up using
tar.

So, are these speeds normal are do I have the ability to get better throughput?

Also, why would the incremental backups on my Linux box be roughly the same 
size as the full backup?  Alot of the
files are music and videos and really don't change.  It's taking around 90 
minutes for a full or incremental backup.

The only other information I can add is as follows:  The drives on the Linux 
machine are SATA drives and on the
windows box I have one SATA drive and one IDE drive.

Just noticed something in the Xfer log for the Linux box which may explain why 
it's doing such a large backup for the
incremental backups:

Running: /usr/bin/sudo /bin/gtar -c -v -f - -C /var --totals 
--newer=2006-02-14\ 11:14:20 .
Xfer PIDs are now 28504,28503
/bin/gtar: Substituting 1901-12-13 15:45:52 for unknown date format 
`2006-02-14\\ 11:14:20'

Looks like there is a problem with the date format and it substituting in a 
date from over 100 years ago.

Appreciate any help.

Thanks.
