All the minimal features work now. - describing a device - describing a backup - link a backup to a device - schedule backups at day intervals - mount the device - put stuff on it - umount the device Downsides: - executed as root, fully! - all scripts are executed as root, dangerous! - Bad and undocumented code.. :) - No tests and only minimal checking (lotta TODOs)
