It won't be of use because BackupPC already performs its own data de-
duplication within the pool.  I suppose I should say it will be of little use, 
since the de-duplication is at the block, not file, level. So that will help a 
little.

The slow data rate of DSL is why you can do that. I'm running 4 over gigabit. 
A single SATA drive (RAID-1 write performance = 1 drive write speed) can't 
keep up with that many seeks and writes at the same time.
