I'm looking for an incremental backup service for Windows.
I really liked Crashplan, and this is almost exactly what I'm looking for, but I need something that can backup to a samba share or ftp or something like that. Crashplan can only backup to other computers running Crashplan, Crashplan's cloud service, or another hard drive on the local machine.
This backup "server" is a Raspberry Pi.
Preferably free or open source solutions.
