peanut, ... isn't it ?

Just don't call it "restore" as it is not it. because snapshot is more like putting literally a sticker on state of your system (which you can go back to and live it again and again).

As you "rollbacks" to a different point, your actual state is preserved under name of rolled-back point with suffix _rollback (to which you can roll over again - with restore you rewrite all with the restored backup).

((and with snapshots and rollbacks there are actually zero data transfers))

Second point goes to "root" as in the example. "root" is limited to system files/applications/settings. it won't affect XBMC settings/library data/addons/addon settings. This is on "home". At the end not important for user so much until "higher functions" like xbianclone/backuphome is working as for user this is not visible.

But the split allows to restore system without touching XBMC and vice versa. "Backuphome" will take just /home/..... and restore just /home again on request. So for instance you want to do a "clean" upgrade from B2 to RC1. You will backup home in B2 (20-xxxMB file). After clean .img flash of RC1 you drop this file to XBian over network and after seconds/minutes XBMC restarts and you have back your XBMC (theoretically regardless of base system).

Again the tech is not so much relevant for the user. Until he is aware that "root" is not all-saver.
