It's probably slow and wasteful to use rdiff-backup for the initial 
mirrors, writing rdiff-backup-data directories that you are just going to 
throw away. Mirror the data piecemeal with rsync first, and once it's all 
in place, use rdiff-backup --force to create the rdiff-backup-data 
directory using the existing files as sources.

Cheers, Chris.
