Same here: I use a rolling release and btrfs. Personally I really enjoy btrfs's snapshot feature. Most of the time when I need backups it's not because of a hardware failure but because of a fat finger mistake where I rm'ed a file I need. Periodic snapshots completely solved that problem for me.

(Of course, backing up to another disk is absolutely still needed, but you probably need it less than you think.)
