Is there an easy way to have the backups encrypted at rest? That's a nice feature of Duplicity. I don't have to worry about someone hacking my backup server or borrowing my USB drive having access to my data.
some ppl have reported using an encrypted storage backend like ecryptfs to store their bup repositories in. that option shouldn't be too hard to put together.
I like & use Duplicity, but it's a little finicky to set up right and some of the more obscure features are counterintuitive or even broken.
