I run btrfs on top of LUKS encryption on my laptop.  You should be able to do the same.

You could then run rsync through ssh.  However, rsync will have no knowledge of any blocks shared under subvolume snapshots.

Btrfs does not yet have internal encryption.

The FAQ says specifically to NOT run BTRFS with any kind of volume
encryption, so you're asking for trouble.

And clearly encryption is not possible if you need snapshots.
