With zfs, you snapshot, and then "zfs send" to another computer. Works great. Only the incrementally changed blocks between the last snapshot and present snapshot need be sent. With btrfs, you *should* be able to do the same thing. But a year ago, there was no btrfs equivalent of "zfs send." I hear they have that functionality now, but I haven't tried it yet. With LVM, you make the snapshot, then mount the snapshot filesystem, and copy the file. Unfortunately, you'll need to copy the whole file. I said earlier in this thread, switch to something zfs-based until you're satisfied with btrfs. That, or run backup software inside the guest. Before I tried virtualbox, I ran ESX, with opensolaris guest inside it, which then exported storage back to ESX host, where ESX would then create additional VM's. ------------------------------------------------------------------------------ Minimize network downtime and maximize team effectiveness.
