This is a big security issue, i'm surprised if no recovery supporting encryption is being worked on (never heard of it actually). What do you think about this?
I have TWRP version 22.214.171.124 and I can encrypt my phone's backups with password.
2nd thing is that you can encrypt whole phone and SD card on Android 3.x and higher (this is not pattern/password/pin lock, this is different) . So even if some techno savvy thief gets his hands on encrypted phone, he must do TOTAL WIPE (wipe data, card, cache etc) to get something like TB working which will wipe backup also.
