This is what I’m doing currently, but it’s not really feasible to have the services shut down hourly for snapshots. This is indeed why I started looking towards filesystem-level snapshotting Obviously I will have other types of backups as well, I’m simply looking to have the on-the-fly immutable snapshot capability here somehow.

Thanks! Can I ask what is your setup like? ZFS on bare metal? Do you have VMs?

Fair about the SSD life. How would you go about achieving the frequent backups without zfs? I wouldn’t want to implement it separately for every app I use, though I’m open to it if this doesn’t work out.

I’ll easily buy more memory if needed, the box now has 8GB and isn’t struggling in any way.
