Great idea!

I didn't know I could it, it worked greatly. The only manual thing now 
is related to grub, but I guess I will not have a solution for that.

Depending on the disk configuration of the target machine, grub gets the 
menu.lst from the wrong disk, or it just don't get the menu.lst file 
automatically, so I have to manually load the menu:

root(hd0,0)
configfile /grub/menu.lst

Could not find a way to solve this, but I guess I can live with this 
problem.

Thanks,
Rodrigo

The approach I am proposing is a little simpler than that, I only want 
to have a bootable usb system which is equal to the backuppc system, and 
which could easily replace it. Of course I will not have all the 
hardware detection that the liveCDs do, so maybe somethings will still 
be done "by hand".

Let me tell you what happened in my tests.

After  33 hours  dd'ing  the pool to the usb disk, it finally ended, so 
I am really considering a eSata case, there is no way to wait 33 hours 
each time I want to sync the server with the usb case.

My experience in booting the usb disk was successful, I had some 
problems with grub and fstab, which I guess are not easy to avoid. 
Depending on how many disks I have on the machine the device is 
recognized as sdb, sdd, etc, so I should, at least, dinamically generate 
the fstab file, which I am not willing to do right now. By now I could 
live with this kind of manual operation.

Below you will find the script I made for doing the sync operation, this 
is a very simple script which only solves my problem, but maybe this can 
help others and maybe you could help improving it. Sorry for some 
portuguese comments...

The restore issue is the reason that targets me to a sort of live system 
which I can easily test and use  any time I want. I prefer to waste some 
time more while doing the backup and than to do a fast backup and spent 
a lot of time to recover it in case of "disaster". That's why I want to 
have this live USB-HD.

Rodrigo

I am feeling it right now, I umounted backuppc partition and the load of

Yesterday I read a little about the LVM snapshot, I didn't know that LVM 
had this feature. When I read that suggestion I thought that snapshot 
was a sort of dd. By now I am running a dd on the snapshot, I opened 
some space on the lvm by reducing the root size and created the snapshot.

Currently I believe that I can stop backuppc and perform the copy of the 
data, but I don't know if in the future it will still be possible, so I 
am trying to do everything considering that the data may change while I 
am performing the copy.

Yes, I have space for everything on the USB HD, I tested the boot from 
it, and it worked fine, so I guess that this idea will work greatly.

I intend to publish this recipe on the Backuppc Wiki, I guess that Tips 
&Tricks is a good place for it, am I right?

I was thinking about running a small shell script that would do this 
adjustments just after the end of the copy process. This script would 
mount the usb partitions e edit those files.

>

This is a good idea, and would simplify the process.

Re-structuring the thoughts, maybe I could do:

  1 - copy the /boot and root partitions just once in a while, or maybe 
rsync it in a low frequency, excluding the files that should be adjusted
  2 - in a higher frequency take a snapshot of the backuppc lvm volume 
to the usb drive

This way I guess some problems would be solved:

  * I don't have to take a snapshot of a mounted and live root system, 
which I guess would cause problems (as said by Tino)
  * I don't have to make that script to adjust everything everytime I do 
a backup

The only problem I see is that I don't have disk space to make a 
snapshot and after it to dd the file to the usb disk, I never used this 
snapshot feature, I will see if I can redirect the file as a pipe 
directly to the usb drive.

I will try to follow this way and see where it takes me. It would be 
very confortable to have this sort of ready to use system.

Let me know ff you have any other ideias, I will send news soon about this.

Rodrigo

[BackupPC-users] Backing up the backup to an external USB drive

[Rodrigo Real]

Hello,

I've been quiet for some months, but I've been trying to read the 
messages in the way I can.

Now I am running to the list to ask a question that has been discussed 
here some time before (maybe many times), but I could not find a 
solution that fits exactly on my needs, maybe I wasn't able to identify 
it...

Let me tell you the full story...

I have a backuppc server with 3 250GB Sata disks running in Software 
RAID-5 with LVM built on top of it. This systems is been running for 
quite some time now. This server is in a different building from where 
we have most of our computers and our servers. But now we got a little 
more paranoid, so we want to backup the backuppc server, and take it 
home. We want to do this process at least once a month, by now we don't 
believe that we need a greater frequency.

So, I bought an USB external drive with 500GB and now I am thinking 
about what is the best way to do it.

My first attempt is to dd each partition of the backuppc server and save 
it as files on the usb disk. This seems to be a simple solution and 
maybe it is good enough. But I was wondering if it wouldn't be possible 
to dd the entire installation, and have a sort of "LiveHD". That would 
be really good and easy to use in case of panic.

My installation looks like this:

/dev/mapper/vg-root on / type reiserfs (rw)
/dev/md0 on /boot type reiserfs (rw,notail)
/dev/mapper/vg-backup on /var/lib/backuppc type reiserfs (rw)

I am thinking about creating 3 partitions on the usb hard drive and to 
dd each of this disks to its corresponding partition. I guess that this 
could work, but I see that there will be some issues:
   * After dd I will have to mount the usb system and adjust fstab
   * I will have to boot on the system on a liveCD to do this, or I will 
have to remount the root system as read-only to run dd
   * install grub on the usb disk (never did this...). maybe some 
adjustments on menu.lst will be needed.
   * don't know if I can boot the usb drive directly on any computer ( I 
guess that this is not a problem since I can get a "not old" computer)

What do you think of this? Does it seems to be reasonable?

Thanks for any comments or help,
Rodrigo

I guess you have two paths to follow. You can directly make backuppc
access your files, which is what you are doing, then backuppc user
must have read acces to all files and read/execute access to all
directories. You can do this adding backuppc user to the groups that
own those directories, and giving the read/execute access to the
group. Somebody once send some tips for using sudo to do this, I think
you can try that if you are familiar with sudo.

Another approach, which I think is easier, is to treat your localhost
as a remote host, and do the backup using rsync+ssh, or tar+ssh.

Hope this helps,
Rodrigo

You can try:

apt-get remove --purge backuppc

This should remove everything, even configuration files.

I guess that you lost the point here, the meaning of
"without-password" in this case is not what you are thinking.

>From sshd_config manual:

`

The main idea is to provide root access through ssh only when the
shared key method is in use. No interactive login for root. This is
another way to prevent from brute force attacks.

[BackupPC-users] ssh, rsync and root access

[Rodrigo Real]

Hello

I've been using backuppc to backup several hosts in a lan. Most of
them are backep up with rsync+ssh using root access. Now I am backing
up a host which is also connected to the Internet, and which does not
accept direct root access through ssh.

I looked at some alternatives and ended up with changing sshd_config
to PermitRootLogin directive to:

PermitRootLogin without-password

I think that this issue would be a good one for a Topic somewhere on
the wiki, maybe inside de FAQ.

I am sure that there are lots of different solutions on this topic.

Best regards,
Rodrigo

The problem seems to be related to the ssh-askpass program, probably
the keys are not corrected configured to work without a password, and
ssh is trying to run ssh-askpass. Don't know exactly how this works,
but if the keys are correct, I think that everything will work fine.

Try to run ssh as backuppc user, to see if you can connect to the
hello.com host.

Good Luck!

I guess DfMaxUsagePct in the config.pl file do what you want:

, /etc/backuppc/config.pl (in Debian)
| # 
| # Maximum threshold for disk utilization on the __TOPDIR__ filesystem.
| # If the output from $Conf{DfPath} reports a percentage larger than

I already had excluded from my list the ones which are installed as
dependencies, If you run an apt-cache show backuppc, both versions
will show rsync is a "Suggests" not a "Depends", the same applies for
bzip2, par2, libfile-rsyncp-perl.

I think that the same will happen at least with Ubuntu, but I don't
have an Ubuntu for testing.

I made some edits for your avaliation. Added this two itens:

Basic Infrastructure - Here we could put things like: Recomendations
for having a safe BackupPC platform, no-breaks and their control
software, LVM, RAID, etc.

Stories - Here we could have a list of pages, where people could tell
us their stories, and show how they use BackupPC.

As we are using Sourceforge for everything, which really seems to be
the best option, isn't that a good idea to have users scripts in a
separate cvs repository under backuppc project? This way we could have a
Tips and Tricks wiki section that points to that code when necessary,
and we get version control, which in a wiki would be a little
complicate.

I think this is a nice idea, but in this case, cvs or svn would be a
better choice. I would like to see a Wiki for things like: backuppc
experiences, backuppc setups (hardware and software), tragic
histories, list of things you should not do, list of things you should
do, etc. The scripts could have a section in this wiki, but I think
that version control is a "must have" when talking about code.

Some time ago I came up with the idea of a backuppc wiki, but it
seemed that everybody (even me) were too busy to take the idea on. If
someone is interested I could provide some infrastructure for this. I
work in a Univercity and have a server with a Trac
(http://trac.edgewall.org/) installation, which could handle a wiki,
svn and ticket system. This could serve a sort of backuppc-contrib
project.

Cheers,
Rodrigo

One of the problems is that you are using the wrong URL, you should
write:
http://:8080/BackupPC

In the way you did, your webserver is trying to find an entry called
"BackupPC:8080", which doesn't exist.

Take a look at $Conf{BlackoutPeriods}, there you can set the days and

I am not sure, but I believe that in this case backupc will keep every
file it transfer, until your full is complete. I think that it will
not keep partial transfered files, so if you have a very large file
that never finishes to download (maybe because of a rsync timeout),
your full will never complete.

Your backuppc will keep trying to complete the full backup before
trying any incremental. You don't have to manually control this.

I am considering that the owner of the computer doesn't want to give
full access to the backup system, or to me. I have a part time job in
a University, and there I don't have control over the desktop
computers. So, my idea is that the users just share something they
want to be backed up, and the job will be done.

Anyway, you can use the script to discover the hosts and C$ shares
that you have access with the admin password.

[BackupPC-users] Automatic Samba hosts configuration

[Rodrigo Real]

Hi Guys

Some weeks ago I sent a message to the list, saying that I would like
to have a Windows Installer for backuppc clients. I never started
that, and started to think that maybe in some cases I could do almost
everything from the server.

So, considering I will do backups using smb transfer method, I only
need that the shares be configured on the clients, and that backuppc
have at least read access.

I made a simple prototype to search for shares on the local network
and to add the machines to the hosts configuration file, and to create
the host specific configuration file in backkuppc config directory.

It seems to be working.

It doesn't have any options by now, you can customize some thinks
directly in the begining of the source code. Please take a look at it
before testing.

I am sending you the file in case you want to give a try and send some
opinions. The script was made with Chicken, which is a scheme
implementation, so you will need it if you want to test the
script. You can download Chicken from here:

Rodrigo

I am not sure, but I think this error means that backuppc is not able
to autenticate or connect to the client host.

In backuppc you don't schedule a specific time for a backup to start,
instead, you specify the wakeup times, in which it will try to do
the backups, and you specify the blackout period in which it will not
do backups. So you should play with this values to make what you
want. 

Also take a look at $Conf{MaxBackups} and $Conf{MaxUserBackups}, which
define how many backups you will do simultaneously.

I also think it would work.

If you are in a hurry, don't try to copy the files, it will take a
long time, and you will have to stop doing backups during this time. I
had a problem with a disk in a LVM last week, I had something like
120GB of data in the backuppc pool, and it took almost 4 days to copy
everything to another disk. Of course, one of my disks had some errors
which slows the copy, but most of the time was spent for re-creating
the hard links.

Take a look at your "Host Summary" screen, and tell us what is the

This seems to be a problem with the samba transfer method, take a look at:

, http://backuppc.sourceforge.net/faq/roadMap.html
| Replacing smbclient with the perl module FileSys::SmbClient. This
| gives much more direct control of the smb transfer, allowing
| incrementals to depend on any attribute change (eg: exist, mtime, file
| size, uid, gid), and better support for include and exclude. Currently
| smbclient incrementals only depend upon mtime, so deleted files or
| renamed files are not detected. FileSys::SmbClient would also allow
| resuming of incomplete full backups in the same manner as rsync will.
`

Maybe this rsync windows package will help: http://itefix.no/cwrsync/

I had never used it, ok? Maybe you could send some feedback about
rsync and windows if you go this way.

Yes, you schedule each of your hosts. You can have a default schedule,
and then you can specify the different ones.

It seems right. What error message(s) are you getting?

Yes, all files will be backed up, it doesn't matter if the backup is
full or incremental. Keep in mind that backuppc stores just once each
identical file.

It seems to be a very good software, it seems to be better than Inno
Setup. I am going to download it and make some experiments.

Would anybody else be interested a project like this?

[BackupPC-users] Automating windows clients installation

[Rodrigo Real]

Hi guys

I am using backuppc with success for at least 3 years, I backup mostly
linux servers, but also have some windows hosts. Some of these
linux machines are through a VPN, using openVPN.

Now I am thinking about backing up some disperse Windows hosts using
the Internet as the network, with the backuppc server in  a safe
place. The idea is that the amount of data on each machine will be
something like 100-200MB.

One of the problems I see are the difficulties related to installing
and configuring OpenVPN on windows, configure the samba shares, and
backuppc. Although this is not a very very hard problem, it is for final
users. 

My idea is to build a sort of installer for this situation, which with
a few questions would do the job. But I don't have any experience with
this kind of thing in the windows world. I believe it could be done
with Inno Setup (http://www.jrsoftware.org/isinfo.php), which seems to
be a nice program, but I never used it.

Do you think it is a good idea to implement this sort of thing? 

The main question seems to be: Is this sort of thing already
available?

Best regards,
Rodrigo

Just check the man page of rsync and found that!

[BackupPC-users] Rsync + SSH and unix domain sockets (was Re: Rebuilding backups file)

[Rodrigo Real]

Rodrigo Real <[EMAIL PROTECTED]> writes:

Hi again

In my last emails I did not told you the full story, because I thought
that it would be irrelevant, but I am experiencing another problem
now.

Before the power loss problem, I upgraded the ltsp server
(independence) I run in this site, and after that, backuppc stoped to
back it up, the problem seemed to be with unix-domain sockets and
FIFOs (represented by p on ls -l output). I was putting all files of
this kind I could found in $Conf{BackupFilesExclude} and running some
tests when I had the power failure.

I already had this problem with unix sockets and fifos on another
site, and I did this same workaround. But I am not very happy with it.

I am running the backups in rsync+ssh mode and have the following
debian packages versions:

, backuppc server
| libfile-rsyncp 0.52-1 
| rsync  2.6.4-6
`

, independence server
| libfile-rsync-perl   0.42-1 
| libfile-rsyncp-perl  0.52-1 
| rsync2.6.9-2
`

I believe that the problem should be with the different versions of
rsync. 

Anyway, in the next week I will upgrade this backuppc system, but as I
have other hosts been backedup by this same backuppc server, I would
like to understand this problem, which is a little obscure to me right
now.

Cheers,
Rodrigo

This file is corrupted also... I think one of the problems I have, is
that this system is running with xfs. This filesystem seems to behave
very bad on power losses. I had a similar problem with another machine
that runs xfs.

I already have another server with the 3.0 version running, but I was
too lasy (or busy) too upgrade this one. I will wait a little bit, to
see if everything is really ok, and after that, will upgrade the
system.

Thanks for the tips, specially for the one about
BackupPC_fixupBackupSummary.

[BackupPC-users] Rebuilding backups file

[Rodrigo Real]

Hi guys

I had a power failure problem on a machine where I run backuppc 2.1.1,
it is a debian system. I was running a backupc_dump in HOST when the
problem ocurred, and the /var/lib/backuppc/pc/HOST/backups corrupted.

The only problem seems to be with this index file and status.pl. I
just removed status.pl, and backuppc re-made it.  I dont know if this
was the best thing to do in this situation, but everything else seems
to be fine.

My question is: is there any way to rebuild backups file based on the
data available in the disk?

Cheers,
Rodrigo

I am not sure, but you could try to quote the date, like this:

/usr/bin/sudo /root/bin/tarCreate -v -f - -C /etc --totals

I use LVM in my backuppc data space. With it you can add/remove more

In 3.0.0 the per-hosts configuration moved to
/etc/BackupPC/pc/host.pl. You should move your files to this place.

I had never tryed that, but I can't think of another way of doing
it. I am sure it is hard to rsync two huge mass of files. Maybe it is
possible to split the rsync process in some parts, but it will still
be hard.

You want some sort of replication?

I think that the main problem of replicating the BackupPC base is that
you must keep the hard links in the copy/synchronization process. I
think that is not (at least, directly) possible with SMB or ftp, maybe
if do some magic using tar, but still, I know nothing about tar and
hard links.

Can't you install rsync on 10.0.0.254? That should be the easiest way,
rsync can preserve hard links with the -H option, additionally it
would transfer only the differences between the two hosts.

Do you have enogh free space on disk?

Take a look at $Conf{DfMaxUsagePct} variable in your config.pl.

Backuppc stops doing new backups when the value in this variable is
reached.

I thinks this is closely related to what is in the plans for BackupPC,
have a look below:

, http://backuppc.sourceforge.net/faq/roadMap.html
| Replacing smbclient with the perl module FileSys::SmbClient. This
| gives much more direct control of the smb transfer, allowing
| incrementals to depend on any attribute change (eg: exist, mtime, file

I think it should be easier to use rsync for now.

For me too, when you create the files using the web interface, that's
where they are created.

The backuppc user have access to all data on your backuped machines,
and depending on your configuration, can execute any command on any
machine. So you must be careful with anything related to it. I never
gave a password for this user, I don't think it is necessary, but you
can do it if you want.

I think you should work on RsyncP to try to solve the root
problem. There seems to be no other way to go ...

Yes, but your home path has some strange spaces, it should be
something like this:

backuppc:x:101:407:added by portage for backuppc:/var/lib/backuppc:/usr/bin/sh

sh usually is in /bin, but I am not sure about Gentoo. If you still
have trouble on this, check your sh path.

You could also use the rsync 'bwlimit' option to a value that make

I have a similar case here and had the same problems when I was
setting everything up. My ClientTimeout is in 8 hours, and I am not
having problems for almost a year.

I know that this is not a good solution for the problem, but if it
works we can use it until we have a better one.

It seems to be a good idea to me, but I never looked to File::RsyncP
code and have no idea of how hard it would be.

You probably don't have a shell or password to backuppc user. Try to
login as root and give a "su - backuppc". If you turn to backuppc
user, you have shell and home.

It is better to not have a password for backuppc, since nobody should
login as backuppc, if you need you just su to it from root.

Try this:
cat /etc/passwd | grep backuppc

to check those things.

I am not sure if I understood your question, but possibly the answer
is 'yes'. This is what I understood: you want to do full backups,
let's say weekly, and _incremental_ (not partial, which is another
thing in backuppc) backups daily. If you need to restore, you will do
it using the last incremental, you don't even have to look to your
last full.

Yes, I think you can use anything you can mount.

Take a look at /etc/host.conf, you should have "order hosts,bind" in
it, to resolve names preferably in /etc/hosts.

You could try to use -W in ping to set a higher timeout, but I don't
think the problem is there, maybe in can find a way to make it work,
but I am quite sure there is something wrong.

For your tests, you could try something like this:

while [ 1 ]; do 
ping -c 1 -W 2 merkur || echo Ping Problem
sleep 1s
done

Gook luck,
Rodrigo

I think you should rename your /etc/backuppc directory, something like this:
mv /etc/backuppc /etc/BackupPC

I think you will need perl-5.8.8 to install File-RsyncP-0.62, but you
can try to compile File-RsyncP first.

The compilation problem (first you had) can be solved commenting 
line 811 in File-RsyncP-0.62/FileList/rsync.h (extern int verbose;
). Just comment or remove that line and try make again.

I don't know exactly what is the best way to do it, but you can try to
define the value of the $TopDir variable to the directory you want, I
think you should put this in the begining of your general config.pl.

I don't know if it will work, but you can try...

Sorry, in fact it should be moved to:

I figured out something similar to your suggestion, but I was a too
afraid to do it :)

I tried this approach, but I never got the free space back, I was
hopping that the nightly routine would remove the files, but it didn't
work, maybe because I did not detect exactly what I should delete.

My problem was solved when I changed $Conf{DfMaxUsagePct} to 99.5. It
seems that with the old value, which was 95, backuppc was not even
starting to remove the backups. When I changed to a higher value,
which permited more disk occupation, backuppc started to remove the
old backups.

I didn't find any tools to manually remove backups, and I still think
we should have one.

I had this kind of problem in many servers. It seems that rsync takes
too long for giving any feedback when it is copying big files. I
usually solve this problem by dividing the backup in many shares,
something like this:

$Conf{RsyncShareName} = ['/bin', 
 '/boot',
 '/etc',
 '/lib',
 '/root',
 '/sbin',
 '/usr',
];

Additionally, you can raise the $Conf{ClientTimeout} value.

Hope this helps.

Good luck,
Rodrigo

No, it works fine, no password asked, and I get root access.

~$ ssh -p 222 -q -x -l root server whoami
root
~$ 

I didn't told you the full story, there was another strange thing
happening with this. The host that I am trying to backup is, in fact,
the localhost.  I tried to configure it as localhost, to backup all
the hard disk, excluding the backup partition of course, but backuppc
only backed up /etc.

Then I configured backuppc to backup localhost, but using his host
name, I thought that backuppc would behave like it was an ordinary
host. What happened is that I am experiencing this problem with the
ssh server port. I know it is stupid to do it through ssh, but I don't
know any other way to do it.

Another question, is it possible to use the hostname as "localhost"
and still backup all the hard disk?

Thanks a lot,
Rodrigo

[BackupPC-users] Backuppc Error: Unable to read 4 bytes

[Rodrigo Real]

Hi guys

I am having a problem with a host that must be backed-up with
backuppc. This host runs an ssh server on the port 222, so I changed
the variable $Conf{RsyncClientCmd} to meet this requirement, but when
I try to run the backup on this host, I receive the error: "Unable to
read 4 bytes". Below is the configuration I am using for this
variable, in this host specific config.pl.

$Conf{RsyncClientCmd} = '$sshPath -p 222 -q -x -l root $host $rsyncPath 
$argList+';

The other hosts which I backup on this server are working just
fine. Additionally, I can manually connect through ssh to this
problematic host. So I think that there is nothing wrong with ssh or
ssh-key.

Had anyone experienced a problem like this?

Cheers,
Rodrigo

I am not very familiar with wake on lan, but you could insert a sleep
in you DumpPreUserCmd.

An easy way to do it is to insert a sleep in the end of wol.sh, if you
don't want to change anything in this script, just do another one
which calls wol.sh for you and insert the sleep in the end.

The one bellow should be enough, save it and put it in DumpPreUserCmd.

---
#!/bin/bash

wol.sh $1

sleep 1m
