Amahi Time Machine
Amahi Time Machine is an App that provides a backup facility that is compatible with Mac OS X Time Machine or similar AFP-based backup tools.
Immediately after being installed, Amahi Time Machine makes your Amahi storage available as a Time Machine target disk. Time Machine is an Apple app for Mac OS X that provides backups. It shows up on the "Shared" area of the Finder on all Mac OS X systems in the network and can back them all up to your storage with little effort!
It has been tested with Snow Leopard, Lion and Mountain Lion.
This version will use the standard disk locations in Amahi to provide a backup share. Later versions may support greyhole-based shares.
