I have the following config option set:
$Conf{BackupZeroFilesIsFatal} = '1';

Here is the output from XferLog (complete output, edited hostname only)

The problem is backuppc recorded this as a successful backup, which is
not too bad, we missed one day backup. However, even worse is the
following day, backuppc tries to do a backup and starts transferring the
entire drive because the previous backup was empty!

The solution for me is to delete the current partial backup and also the
previous empty backup, then let backuppc run a new backup.

Adam
