Please remember to disconnect the remote drive, physically if possible, whenever it's not being actively used. It'll be a pain to reconnect and disconnect each time, but if (Heaven forefend) your system gets infested by a wiper, it'd compound your misery by going looking for remote backup media.

Oh, and I'd say "test you can restore from your backups", but I won't need to say that in present company. End of core dump.
