This is for the (still experimental) support for accessing remote backup devices, that is, devices of another machine. The way it works is very similar to the rmt(8)demon. KBACKUPwill call a remote shell and redirect the data to a MULTIBUFprocess running on the remote machine.
On the remote machine, at least MULTIBUF, dd(1)and the archive handler ( afio(1)or tar(1)) have to be installed. It is best, if you install the complete KBACKUPpackage on both machines to make sure everything is available.
NOTE: Remote mode does currently not work with autodetection of devices (it will always detect local devices only) and will not work with multivolume archives. Therefor all your archive has to fit on a single volume! This will be fixed in a later release.
