[rdiff-backup-users] Using a plain rsync for initial backup?

[Casey Rodarmor]

Hi there!

I've got two servers A, and B, and my laptop. My backed up data from
my laptop used to live on server A, but I plain rsynced it from server
A to server B. Now I'd like to create an rdiff-backup on server B from
my laptop, but I want to make sure that it uses the data already
present, instead of trying to copy everything over fresh. Any advice?

Thanks a bunch!
