I try to backup a OpenVZ host with backupPC. For some other servers I've
a working rsync configuration that backups the whole file system. But
with this server I would like to backup the shares separately (because
of the many mounts that OpenVZ have for different /proc /sys and so on..).
When I use the BackupFilesExclude-option I notice that the remote
rsync-server sometimes "goes away". There are no running rsync-server on
the server and backuppc only displays one XFer PID on the status page.
That PID is the local one, no remote. Then I have to select
"Stop/Dequeue Backup" and then the backup continues on the next share.
If I run a full backup again it may succeed, or fail on another share.
The config for this host:
----
$Conf{XferMethod} = 'rsync';
$Conf{RsyncShareName} = [
'/',
'/boot',
'/mnt/backup',
'/var/lib/vz',
'/mnt/pbxdata'
];
$Conf{BackupFilesExclude} = {
'/mnt/pbxdata' => [
'/pbx_test/recordings', '/pbx_test/recordings2', '/heartofgold'
]
};
$Conf{RsyncArgs} = [
'--numeric-ids',
'--perms',
'--owner',
'--group',
'-D',
'--links',
'--hard-links',
'--times',
'--block-size=2048',
'--recursive',
'--checksum-seed=32761',
'--one-file-system',
];
----
This is an excerpt of the log where the backup got stalled on share

Got fatal error during xfer (No files dumped for share /var/lib/vz)
Backup aborted by user signal
Saving this as a partial backup, replacing the prior one (got 41684 and 3 files versus 0)
Does anyone have a solution for this?
Thanks!
