Re: [BackupPC-users] Discrepant file size reports of backups
Hi, Are you using the backuppc deb from ubuntu? If so, you seem to have modified topdir incorrectly. You're right, that's the case. I did not install it myself and didn't notice the directory was moved. the pool, cpool and pc directories *must* all reside on the same filesystem. Also, you can't simply change topdir in the config file. See https://sourceforge.net/apps/mediawiki/backuppc/index.php?title=Change_archive_directory for details. Both directories are in the same filesystem and the path was most likely changed right after the installation. I don't fully understand why the changed path is a problem in this case, but I can try to move the directory back to the default path (thanks for the link). regards Stefan -- Come build with us!

I don't fully understand why the changed path is a problem in this case, Neither do I, but I remember that it *is* a problem. You can have a link for $TopDir (i.e. $TopDir = '/var/lib/backuppc' and /var/lib/backuppc is a softlink to somewhere), but softlinks below $TopDir don't seem to work (whatever the reason was), even if they remain within one file system. but I can try to move the directory back to the default path (thanks for the link). That case is not really covered on the wiki page, because it really depends on what you did and thus need to revert. I was hoping the wiki page will explain some of the background. If you need more help, we'd need to know a bit more about your filesystem layout (i.e. 'df', any softlinks involved, layout below /usr/share/backuppc/data, ...). If it's really all just one FS, you probably just need to 'mv' some things around, though that won't re-establish pooling if it wasn't working. Also note that backup expiration is *not* done by BackupPC_nightly but by BackupPC_dump. Changing the number of backups to keep and running BackupPC_nightly (via the daemon, hopefully? :) will do exactly nothing. You need to run a backup to expire old backups, and if pooling isn't working (not sure from the info so far), you won't even need BackupPC_nightly to get back some space. On the other hand, moving things back into place just might make BackupPC_nightly clean out the complete pool (because nothing has more than the one pool link) without the need to expire any backups. That would however mean that your existing backups do not participate in pooling (I believe Jeffrey has scripts to fix that, but I'm not sure if it's worthwhile for you). If you don't need to keep your backup history (as your attempt of reducing the number of kept backups suggests), you might be best off to simply start over with a new pool (and keep the old one around as long as you need it). Consider putting this on a separate partition (or better yet: set of disks) from your OS installation. But that matter is explained on the wiki page :). Regards, Holger -- Come build with us!

If you install from source from the sourceforge code, there is an install step that modifies something in the code with the location you choose for the directory. However, packaged installs (.deb/.rpm) have already done this step so you can't alter the location. But I thought this was changed in the latest version. Regardless, the easy approach is to mount the filesystem you want to use at /var/lib/backuppc before installing the package. -- Les Mikesell lesmikes...@gmail.com -- Come build with us!

[BackupPC-users] Discrepant file size reports of backups
Hi,
we have a problem with our backuppc server. The disk is almost full, but
the reported size of the backups is much less. Additionally, the pool is
reported to be empty in the CGI.
I tried to set all backups (full and incremental) to a minimum and
maximum number of one and run a nightly cleanup. No data is deleted at
all, the pool is reported to be emtpy.
Can someone explain why the reported sizes (see below) are that
different? Is there orphaned data in the pool directory and how can I
clean it? Any other ideas?
OS: Ubuntu Server 8.04 LTS
Backuppc 3.0.0
$Conf{TopDir} = '/usr/share/backuppc/data';
$Conf{ConfDir} = '/etc/backuppc';
$Conf{LogDir} = '';
$Conf{InstallDir} = '/usr/share/backuppc';
$Conf{CgiDir} = '/usr/share/backuppc/cgi-bin';
This is what the host summary shows on top:
* 19 full backups of total size 274.58GB (prior to pooling and
compression),
* 13 incr backups of total size 24.86GB (prior to pooling and
compression).
