If Linode supports ZFS, you could use ZFS send-recieve to make backups to your local machine. But like I said, the ZFS storage driver probably hasn't been well tested.

nope. no backup for anything other than EXT4. Its really weird and limiting.
I mean LVM volumes have to be pretty standard right ? (I would argue more standard than ZFS).
Oh well, should have done this long ago.
