Re: [rdiff-backup-users] rdiff-backup painfully slow using NFS mount

[Dean Cording]

rdiff-backup gets most of its advantage by running running a server process on 
the destination machine that keeps a lot of the disk access local.  When you 
run rdiff-backup on a networked drive you lose this advantage because the 
client and server processes bot run on the local machine and all disk access 
is across the wire.

You might find Duplicity (http://duplicity.nongnu.org) is better suited to your 
arrangement.  Duplicity also uses the rdiff algorithm but it keeps the metadata 
locally and creates local backup archives which are uploaded when completed.
