To amplify what Les just explained, this whole idea of "pool
deduplication" is one of the key selling points of BackupPC, alllowing
you to backup all your machines ever day -- whether as fulls or
incrementals -- with only minimal additional storage requirements.

Also, to answer your other question about minimal file length for the
pool, all non-zero length files (including the 'attrib' database
files) are stored in the pool.
