Restore only changed files with duplicity

Question

Hello Guys,

I've a problem. Duplicity is perfect for backups, I love so much that can be able to do incremental diff tars, but ... when restoring duplicity seems don't apply same concept.

Basically I need to restore only changed files (obviously after a full backup) but I can't figure how do that.

When I try to restore a directory I get:

Restore destination directory /Volumes/Data/Backups/Srv1 already exists.

I need to backup a directory (and I don't have any problems in doing that) and setup a mirror on another machine.

Thanks!
