[BackupPC-users] access backups created by different server

[Michele Z. <m....@gm...>]

Hello,

Is it possible to access backups created with a different machine?

My backuppc server died, but /var/lib/backuppc was on a different disk 
so I still have full backups of localhost.
Ideally I would like to restore the full system but it would already be 
very good to recover the mysql databases and selected system 
configuration files.

I reinstalled ubuntu, reinstalled backuppc, relinked /var/lib/backuppc but
- No joy with the GUI (old backups do not show)
- No joy using the command line.

(as backuppc user)
$ /usr/share/backuppc/bin/BackupPC_tarCreate -h localhost -n 224 -s '/' 
/var/lib/mysql > /tmp/dbs.tar
/usr/share/backuppc/bin/BackupPC_tarCreate: bad backup number 224 for 
host localhost

- BackupPC_zcat works but I have not figured out how to restore 
user:group and permissions

Is there a way to get the GUI to read the backups (I am lazy)? If not is 
there a way to trick BackupPC_tarCreate?

Note that when I re-installed backuppc it probably wrote new files in 
/var/lib/backuppc/pc/ and I do not have backups of those.

Cheers,

Michele

As I remember almost all settings are stored in the .conf file. Here is 
a blog post when I needed to move the pool a few years ago...

http://blog.trebacz.com/2009/10/my-weekend-linux-maintenance-activities.html

It has a link to the SourceForge thread that I found helpful also. Great 
think is backuppc hasn't changed much since then...

It would help if you provided the error messages you get with the gui in 
the logs...
However, my guess is that the userid/groupid for the new install doesn't 
match the old. You have two choices:
1) Uninstall backuppc, remove the user/group backuppc, manually create 
the user/group backuppc but make sure you match the userid/groupid on 
the files in /var/lib/backuppc....
2) Re-mount /var/lib/backuppc and map all existing files to the new 
userid/groupid that the backuppc user has.

Another possibility, you need to re-create the config files and/or hosts 
file.... The contents probably don't matter a lot, as long as the 
hostnames match the old ones (see /var/lib/backuppc/pc/ for the right 
names).

Hope that helps....

Regards,
Adam

Hi,

the configuration is in /etc/backuppc there is a hosts file which defines the active hosts. It could be enough to add the host you wish to restore to this file.

Thanks guys,

I found out that the issue was relatively trivial: the file "backups" in 
the root localhost (/var/lib/backuppc/pc/localhost/backups) was 
overwritten when backuppc was reinstalled so that it only had one entry.

I guess it could be possible to re-build the previous backups using the 
file backupInfo within each backup but it is too much work.
Instead I renamed the last directory with a full backup (in my case 224) 
0 and I was back in action.

So the (partial) solution was simply:
mv /var/lib/backuppc/pc/localhost/0 
/var/lib/backuppc/pc/localhost/0.original
mv /var/lib/backuppc/pc/localhost/224 /var/lib/backuppc/pc/localhost/0

Michele

really? As in

	su - backuppc
	/usr/share/backuppc/bin/BackupPC_fixupBackupSummary

? Admitted, you might need to delete the single entry from the backups file
first, but it will probably work equally well if you don't. Why is there an
entry anyway? Does your distribution ship BackupPC with an initial backup
for localhost? ;-)

Well, yes, but you lose your backup history, and you'll probably run into
problems when you try to do backups ...
