There are sensitive info here, so I can't share it (secret keys, x509 cert +
key, password for storage etc.). But my guess is that the issue is not with the
content, but with the FS. Maybe the client rsync can't open the file (du to a
bad interaction with pmxcfs, or a lock problem), sending an error code not
correctly handled by rsync-bpc. The problem might even be related to the fact
that I backup several PVE hosts in the same cluster (so, same /etc/pve, that's
why I think of a locking issue) at the same time.

That's just a cosmetic issue, du to the fact that I've set $Conf{TopDir} to
'/var/lib/BackupPC/' (with a trailing slash).
