it's really not that hard. I've set up backblaze which is reasonably cheap. with the help of AI I was able to setup a permanent cron job that backs up everything from local into B2 using rclone, which client side encryption. It's epic. I haven't looked at it for a while but I do DR test every once in a while a small subset and it works really well. I use postgres as DB and this is the big one to back up daily. Rest is just the increment. Can be further optimised I guess but I'm happy with it.
