(Is it?)
I don't really think so, but an empty *uncompressed* file is trivial to find with "find", presuming you can get yourself to accept its syntax ;-). I don't think BackupPC distinguishes much between compressed and uncompressed files (it's just a parameter to most methods). Of course, the bug could be in the code that finally handles compressed files, but my gut feeling is that it's in the pooling code (presuming there actually *is* a bug, that is). > Personally, I feel that compression has no place in backups.

If you can't get back your file from the most recent backup, because it has somehow been corrupted, there's not much chance to get the same content from any other backup. In other words, deduplication *is* a form of compression ;-).
