My current backup system involves having all my data on ZFS and then using sanoid for snapshots and syncoid for syncing those snapshots to my server that also runs ZFS. Would I gain anything significant from switching to something like Restic for backups?
I use syncoid to sync to a server that only has 1 open port, ssh, which only allows one user, and that non root user runs rbash and can only do zfs receive, not zfs destroy. Hopefully that stumps the ransomware people trying to delete backups.
