Replication is not backup. It only protects against hardware failure.
Spinning disks are good though. A lovely spot for backups. Just put them in a different building.

- InclinedPlane 17y agoIt doesn't matter if your data is replicated across 3 different continents. If all of your data is accessible behind the same admin login, or if it is all vulnerable to the corruption in the original, then it still has only 1 point of failure. A proper "spinning" backup is an immutable journaling system that can't be trimmed except via extremely secure methods (e.g. physical access to the machine).
