Because theres no perfect solution at the moment we have opted for a 4 disk setup, and mirror them all using ZFS. We also do 10 minute snapshots, and incremental snapshot backups (to S3). Feels safe enough for our needs. Before this we didn't have 10 minute snapshots of all our data so this has actually allowed us to recover from dev errors as well (if they were to happen). We do have our DB running in a container + mounted volumes that use the above configuration.
