I was running a backup of about 150 GB of data three (home directories) 
about 3 times a day, and it was taking 8 MB per incremental backup with 
rdiff-backup 1.0.5, even if nothing had changed. It may well be less with 
more recent versions, due to (1) compressed metadata and (2) incremental 
patches to metadata.

Cheers, Chris.
