That had gone through my mind - how much RAM do you have in the backup system ? Also what other options do you use - I've found some of them (especially hard-links) can have a significant impact on performance.

Otherwise, have you looked at StoreBackup ?
It's probably somewhat more than you are after, *but* it does have a mode specifically for efficient transfer of backups from one system to another. I've been using it for a few years for my backups (keeping multiple backups etc) but haven't used the remote transfer bit yet.
