Under that are BTRFS subvolumes named for the LAN systems they back up, such as hex, droog, etc. Also under backups is where the snapshots are made, such as hex-snap-2012-10-15, droog-snap-2012-10-15, and so on. So where can I encrypt? Do I have to go in to each subvolume and make private directories for each of those subdirs like bin, etc, lib, and so on? If so, how would I update the new snapshots which are created, for encryption? It doesn't seem possible to encrypt a BTRFS subvolume, and certainly not an array?
