TWRP, Encryption and Cyanogenmod 12.1

I’d like to encrypt my phone just to try it. But, being cautious I’d like to make sure I can restore the thing if I want to. By, "restore," I don’t care about decrypting it, but I sure want TWRP to still be able to restore a previously saved backup.

If, after encryption, TWRP will not be able to restore then I think I will pass on the encryption as it will be too much work to reconfigure a new CM install.

So, the question is, if I encrypt, will TWRP (current version) still be able to restore a saved-backup or would I have to revert to ADB and a new install of CM12.1?

Thanks
