Hi,
you can always force a full recheck on the nightly by increasing the
PoolNightlyDigestCheckPercent config entry to 100 (% = full pool).
But: this will detect issues, but not correct them. The warnings you see are an
indicator of data loss on your server instance, and BackupPC can't magically
restore lost data. (It can backup again what still exists on your hosts, of
course, but that's about it.)
With _very_ high probability, you are experiencing not a problem of BackupPC,
but one of your server. Likely, a hardware failure or hiccup due to power loss
or random crashes of the system. I recommend to check the kernel logs for
suspicious entries and error messages and to have a look at the drive status
(e.g., via SMART readings).
Cheers,
Alex
