I had a similar issue when going from Debian 10 to Debian 11, where the
upgrade kept the old settings in place.
In the end, these changes had to be made:
- Install backuppc-rsync debian package
- Define it's location in the main config.pl file (/etc/backuppc.config.pl
in our case). The line required below:
*$Conf{RsyncBackupPCPath} = '/usr/libexec/backuppc-rsync/rsync_bpc';*
This got us to a position where most backups worked, but some would still
fail from older Debian Stretch and Ubuntu 16.04 installs. For these to
work, we had to change our configs from whatever custom config we had, to
be as below which is closer to the current BPC version 4 default config:
*$Conf{RsyncArgs} = ['--super','--recursive','--protect-args',
'--numeric-ids','--perms','--owner','--group','-D',
'--times','--links','--hard-links','--delete','--partial',
'--log-format=log: %o %i %B %8U,%8G %9l %f%L','--stats',];*
The above was done inside all of the .pl config files for all hosts, as we
use a separate file per host.
Hope this helps!
