Try to enable verbose logging in /usr/local/psa/admin/conf/panel.ini

[debug]
enabled = on

[log]
filter.priority = 7
show.util_exec = on
show.util_exec_io = on

and in /usr/local/psa/admin/share/pmmcli/pmmcli-rc

FORCE_DEBUG_LOG 1

and try to find errors in
- /var/log/plesk/panel.log
- /var/log/plesk/PMM/migration.log

It looks like the file backup_xyz.de_2002120547.tar is empty and cannot be rotated automatically.

OK I changed the backup from daily full to incremental and now after a few days back to daily full. Obviously this was enough and the system healed itself.
