Is there any good resources to look at when looking for best practices in regards to backups? I'm currently looking at the docs on rancher + kubernetes and I'm curious to see what the other folks are doing. I've currently set to store our backups on ceph with hourly recurring backups with secretbox encryption. I do think the hourly back up is an overkill and using kmsv2 is the way to go once we get to v1.27+. Any thoughts?
