rsync won't work if you've got snapshot volumes though (unless
you're prepared to have a backup copy thousands of times the
size of the original or have a framework in place to replicate
the snapshots on the backup copy as soon as they are created
(but before they're being written to)).

To backup a btrfs FS with snapshots, the only option seems to
be to copy the block devices for now (or the other trick
mentionned earlier).
