Nice! Also cool that you got hold of a Zero! I have heard only of those in legend.
Absolutely! the easiest way to do that, I think, would be to encrypt the volume itself. I use LUKS for this. I'll make a note that this would be a good topic for a future article, but the short version is that LUKS is native to Linux, so as long as your Pi and computer are each configured to mount and decrypt the drive, they will each freely read and write from the volume. No problem. Since rsync uses SSH, the traffic itself is also encrypted.
Any other computer that the drive is plugged into, of course, will not be able to decrypt the drie, unless you yourself provide credentials.
