As far as backuppc itself is concerned, the backup just isn't complete 
and if it was a full rsync-type it will try to re-use what it got on the 
next attempt.   On the other hand, the filesystem itself can be 
corrupted and different OS's and filesystems have different ways to 
protect against that and to recover if it does happen.
