Can anyone recommend a secure, open source, offsite backup setup with client-side encryption? The way I’m set up now, I have certain folders on my QNAP NAS automatically backup to Backblaze. Which is fine, except that the QNAP encryption scheme is proprietary and Backblaze is also proprietary (I’ve had a good experience with the latter, tho). I find the QNAP in general kind of hard to use, but it’s what I’ve got at the moment. I was contemplating using Cryptomator, either with BB or something else, though I’m not exactly sure how to set it up. So what do people think? Would another setup be slightly better? If it ain’t broke . . . ?
