I've used a full backup to migrate from hard drives in the past; it's actually faster to sync drives than fetch packages off the internet, and my system is exactly in the same *state* as it was left (including those bookmarks in Icecat, those cached emails, etc.). Keep in mind that multiple subvolumes can be used to hold your 'home' or other data partitons, making these individually easy to snapshot and backup. Maxim
