[BackupPC-users] REQUEST FOR ADVICE ON SUITABILITY OF BACKUPPC

2008-10-28 Thread SamK

Many thanks for the your replies.  It is always encouraging when existing 
members of a forum respond so quickly to a request from a new member.

An accurate summation.

This was my intention, but omitted from the original post for the sake of 
brevity.  Any further suggestions of this type will be gratefully received.

This was precisely the type of insight I was hoping to receive from experienced 
users.  Very helpful.


Rob Owens wrote:
> The documentation is very long, but it provides a lot of very helpful

I fully agree with this point of view.  The documentation formed part of the 
initial research conducted to help establish that BackupPC might be a suitable 
candidate for my requirements.  The number of configuration options can be 
difficult for a new user of the product to know what is required to obtain a 
basic working confuguration upon which tests can then be performed.  It was 
from this position that the advice of existing forum members was requested.


FEEDBACK ON SUGGESTIONS
* Proof of concept has been successfully established based upon using multiple 
'hosts' and aliases in accordance with the advice received.
* Smb has been used at this stage and rsync will be investigted as an 
alternative.
* The ability for BackupPc administrative user to copy all backups to external 
(removable) disks for disater recovery purposes will be investigated once a 
working setup of the other items in the wish listed has been established.


QUESTIONS
01 What are the benefits of using rsync rather versus smb?
02 Does the choice of rsync or smb affect the off-site copies on removable 
disks for disaster recovery purposes?
03 Is it possible to use Samba domain accounts with backuppc rather that the 
default Apache htpasswd?
04

How is the assignment of multiple groups conducted as opposed to using a list 
of 'moreUsers'?

05 When logging into BackupPC as a user is it possible to:
  (a) force the web page to defualt to displaying 'Browse backups'?
  (b) remove from the left-hand side-panel under aliased hostname section; all 
options except 'Browse backups'?
  (c) remove from the left-hand side-panel the entire 'Server' section?

[BackupPC-users] How do you remove spurious backup?

2008-10-28 Thread Jeffrey J. Kosowsky
I have a "spurious" backup of one of my machines that shows up on the
web interface as a backup but when you click on it you get the error:
"Error: Directory /var/lib/BackupPC//pc/mymachine/0 is empty"

Looking in /var/lib/BackupPC/pc/mymachine, I see that indeed there is
no "0" directory.

Indeed, there are is all no XferLog.0.z either.

However, backup '0' is still included in the file 
/var/lib/BackupPC/pc/mymachine/backups.

Restarting backuppc did not fix this problem either.

Now, I ending up fixing the problem by manually editing the 'backups'
file to remove the '0' line but I was wondering if there is a better
way...

Thanks

Le wiki page looks fine to me. I can therefore schedule backups "full" over the 
weekend and "incr" them during weekdays. 

I'm not the backuppc user (my english is slighter better !) : is there a way to 
force backuppc just to use the crontab ?

Or, since the default scheduler does fulls once a week, you can just use 
the web interface to force one at the time you'd like them to happen. 
Incrementals will subsequently run (approximately) every 24 hours from 
then and fulls every week. Even easier - just add new machines at about 
the time you'd like their full backups to run - or as you are leaving 
work on Fridays.

Yes, you simple disable regular backups via $Conf{BackupsDisable} = 1;
Then run the backups "manually" via crontab using BackupPC_serverMsg as
described in the wiki page.

HTH,

Apart from top-posting, you have posted a commercial email to this
mailing list. I don't want to be seen to encourage you, and sure, a
number of people on the list just might be interested. Except, you
didn't tell us what it is you are selling!

Apparently you have a "pendrive" which I assume is some USB flash memory
stick type of product. Then you tell us "Only you need simple machine
with all the hard disk that you want and usb port.". I guess that means
we buy some memory (probably with some software on it) and then we buy a
whole machine, and then it does lots of stuff. Kind of like buying a
machine, installing debian, and installing backuppc, etc except you
wouldn't need to buy any "pendrive"...

So, I'm confused... Feel like telling us what it is you sell and more
importantly, why we would want to buy it?

Adam

How is the assignment of multiple groups conducted as opposed to using a list 
of 'moreUsers'?

06 When logging into BackupPC as a user is it possible to:
  (a) force the web page to defualt to displaying 'Browse backups'?
  (b) remove from the left-hand side-panel under aliased hostname section; all 
options except 'Browse backups'?
  (c) remove from the left-hand side-panel the entire 'Server' section?

The benefits are basically that rsync will more accurately backup the
correct files for incr and full backups, actually, the main advantage is
when you have limited bandwidth between server and backuppc because
rsync will send less data over the network.

If both sides are Linux, then I think everybody strongly suggests using
rsync + ssh.

> 02 Does the choice of rsync or smb affect the off-site copies on removable 
> disks for disaster recovery purposes?

No, no difference at all. Basically, using smb might result in some
files not being backed up in a incr, (ie, files with old date/timestamp)
and so that will produce a different archive, but other than that, both
rsync/smb/tar/any other method will result in the same archive.

> 03 Is it possible to use Samba domain accounts with backuppc rather that the 
> default Apache htpasswd?

Well, backuppc uses the authentication provided by apache, which by
default, is htpasswd. You can configure apache to do authentication via
smb, and hence you can get backuppc to use smb auth. If you choose to
implement this, I would suggest working through the apache communities
on how to protect a simple html page using smb accounts, and once you
have that working, then move on to getting it to work with backuppc.

Not sure, I don't use backuppc v3 yet... I know you can alter the

links to sourceforge, faq, etc At the end of the day, it is

all open source, so you can change anything you need. Not

that I would recommend this, since it will be harder to

maintain in the future.

BTW, please consider subscribing to the mailing list instead of posting
through backup central.

Yes, you simple disable regular backups via $Conf{BackupsDisable} = 1; 
Then run the backups "manually" via crontab using BackupPC_serverMsg as 
described in the wiki page.

And thereby useless. Do you really think anyone will look closely for what you
might have changed from your previous post? Remember, this is a mailing list,

Jeff, just letting you know that I've been silently cheering you on.  I
have intermittent problems with rsyncd hanging while backing up my
Windows machines, and I hope you find a cure!  Unfortunately I don't
have much assistance to provide.  I can only say that backing up my
Linux hosts (rsync over ssh) works more reliably than backing up my
Windows hosts (rsynd).  I do get successful backups of my Windows hosts
via rsyncd, but I also get hangs more often than I'd like.

Rsync only transfers the changed files -- even on full backups.  Smb
will require a periodic full transfer of all files.  Basically, rsync
requires much less bandwidth if you have a fairly large amount of static
data.

rsync is *way* better if you're doing backups over the internet.

I think all authentication has to be done through Apache, but it doesn't
necessarily have to be htpasswd.  I saw a post on this list recently
where someone explained how to set up LDAP authentication for Apache and
make it work with BackupPC.  So I suppose it's possible to use Samba
domain accounts, but I can't give you instruction on it.

Hmm, I thought you could do groups, but maybe I'm confused.  Does
anybody know if it's possible?  What if you create an htgroup and enter
that group name as "user" in the hosts configuration section?

Admin-type stuff does not appear on the screen if the logged-in user is
not an admin.  (For instance, there will be no option to edit the global
config file).  Anything else can probably be removed if you dive into
the cgi code, but I don't think there's a simple "for dummies" set of
instructions -- I asked about that on this list a few months back.

Yes. If you disable backups, BackupPC will not do anything any more

Depending on the amount of RAM you have relative to the size of the 
archive, you might be able to rsync the whole thing to a copy elsewhere 
but with large archives the number of hardlinks can make this 
impractical.  Otherwise you can image-copy the drive or set it up on a 
mirrored raid where you rotate one of the mirrors offsite periodically.

> QUESTIONS
> 01 What are the benefits of using rsync versus smb?

Less bandwidth use, more accurate incrementals (detects removed files 
and new ones copied in with old timestamps).

> 02 Does the choice of rsync or smb affect the off-site copies on removable 
> disks for disaster recovery purposes?

No, the archive ends up the same.

> 03 Is the archive mechanism suitable for use as a disaster recovery tool?

'Archive hosts' end up generating a tar image. If you know how to 
reconstruct from a tar image you are all set.  If you come up with a way 
to duplicate the entire archive partition, you'll need an installed copy 
of backuppc to access it.

Apache has a large number of mod_auth_xxx modules for authentication. 
You can do this with mod_auth_pam but it isn't included in most 
distributions and there may be better ways.

I didn't think you could use group names in the hosts file.

If you don't log in as an administrator you only see the hosts where you 
  are listed as the owner and all you can do is start/stop/browse.  But 
the whole web site is generated by a perl script that you can modify if 
you want.

Is that a off-site backup that uses any sort of rsync like algorithm to
minimise the bandwidth used?

If it is, you might like to get it to backup the cpool/pool and then use
the pctar utility (forget it's name) which AFAIK creates a tar file full
of the links. So your offsite backs up the pool + the small tar file.
That way you could restore *ALL* your backup data

PS, I don't know how truly practical the above is, but it may be an
option? Can anyone comment on whether that might be a useful way to get
an off-site copy of your backuppc server?

Adam

Re: [BackupPC-users] force full save on weekends

2008-10-28 Thread albertomarconi
Hello,

I developed a patch for my personal use and it has been working successfully 
for more than a year. It has the purpose of restricting the schedule of a 
backup to a definite time window and breaks up the default logic of starting a 
backup as soon as a computer is on the network.

I attached a tarball to this email. Inside the tarball there are a patch file 
for BackupPC 3.1.0 and another patch file for BackupPC 3.0.0. Their names are:
 RecurringBackups-3.1.0-v1.patch
 RecurringBackups-3.0.0-v1.patch

Installing the patch is simple:
 backup your configuration files;
 unpack the sources of BackupPC;
 change current directory to the unpacked sources;
 execute "patch -p0 -b < /path/to/the/patch";
 stop backuppc;
 execure "perl configure.pl" and proceed as you would for a product upgrade.
 start backuppc;
 configure the new feature.

You shoud configure WeeklyBackups, DailyBackups, WakeupSchedule,
BlackoutPeriods, FullPeriod, FullKeepCount, IncrPeriod, IncrKeepCnt as a 
minimum.

Instructions are given inside the config.pl file, however, I shall add some 
notes I derived from my experience.

- In the patch documentation I suggest using blackout periods along with 
recurring backups. Nowadays I never use blackout periods anymore, it is simpler 
to have recurring backups scheduled explicitly, in fact I am used to remove 
all BlackoutPeriods from my configuration files.

- I noticed that the first time I add a new host to my backup server, its 
backup starts at the first WakeupShedule occurrence even if the occurrence is 
outside of all configured time windows. I consider this a minor bug and I have 
not investigated it as I am used to manually start a full backup of any newly 
added hosts.

- I noticed that all my backups run twice when my servers leave DST time and 
enter non-DST time. I have not investigated this bug as I consider it a minor 
flaw. It happens that once in a year I execute two backups instead of one for 
all my hosts. Not so dangerous.

- Care must be taken when scheduling nightly backup jobs as they can overlap 
the "non-DST to DST" time frame. Once in a year you risk that your backup jobs 
will not be executed if you schedule them to occur in the same time window 
adopted for "non-DST to DST" transition. For example, once in a year the time 
window between 02:00 and 03:00 does not occur for servers in CET time zone when 
the transition to CEST occurs. Usually I adopt a time window which includes the 
transition window, for example: 01:00 to 06:00.

- You can run many backups per day without recurring to any cron jobs.

- The web configuration is supported, you are not required to manually edit any 
configuration files, look at the "Schedule" section.

I hope my experience will be helpful. Any suggestions are welcome.

Not that I have used it/etc, but I have heard that ATAoE would be an
ideal solution for this. It would be interesting to hear about off the
shelf NAS solutions which support ATAoE (or can be co-erced to support it).

If you were able to recompile the kernel on your NAS to add NFS support,
I imagine you could add ATAoE support apparently it is quite simple,
I think other people have even posted examples of how easy it is to
setup to this list in the past.

With rsync the only way to do compression is by using ssh and getting
ssh to do the compression. (Or doing it over a VPN where the VPN
software compresses the data, or something similar).

You can't use rsync compression.

[BackupPC-users] Backup_dump - Wrong User

2008-10-28 Thread Huxtable, Brian R.
I've recently needed to reinstall BackupPC on Mac OS X 10.5 Leopard.
While it had worked previously on this platform, I'm getting some very
odd errors that driving me insane:

 

I'm able to run backups for a period of time but some point in time
during the day I'll begin to get repeated iterations of the following:

 

/opt/local/BackupPC/bin/BackupPC_dump: Wrong user: my userid is 501,
instead of  (tlctoor)

Please su tlctoor first

BackupPC::Lib->new failed

 

After I get this, newly initiated processes will fail but previously
active processes seem to continue.  I then need to restart the BackupPC
service to get backups back on track.

 

What am I missing, where should I look?

 

Brian

Yes I am sure. I've installed rsync as a vista service and it runs as user

[BackupPC-users] Little thoughts to share - RSYNC MAC SSH

2008-10-28 Thread Pedro M. S. Oliveira
Hi all!

For some time I had trouble with rsync and ssh.
My problem was that the ssh connection would stop after a few seconds
with this error in backuppc log:

Got fatal error during xfer (fileListReceive failed)

and in the /var/log/messages:

Disconnecting: Corrupted MAC on input.

After searching for a while and doing some digging i found that i had
files that would cause ssh to exit, usually you can exit ssh with "~."
and in fact i had files with that name and content.
what i did on backuppc config page was:
on the main configuration editor, xfer:
RsyncClientCmd
$sshPath  -q -x -l root $host $rsyncPath $argList+
changed to
$sshPath -e none -q -x -l root $host $rsyncPath $argList+
RsyncClientRestoreCmd
$sshPath -q -x -l root $host $rsyncPath $argList+
changed to
$sshPath -e none -q -x -l root $host $rsyncPath $argList+

this will avoid escape caracters.

what do you guys think on putting this by default on the next release?

cheers,
Pedro

I think this makes perfect sense. I would *expect* it to have "-e
none" by default.

The 'net used to be run by smart people; now many sites are run by
idiots. So SAD... (Sites that do spam filtering on mails sent to the
abuse contact need to be cut off the net...)
