My time machine share is backed by ZFS. I have a separate dataset for each laptop, with snapshots retained for 30 days. As long as I know roughly the last time the backup worked, I can restore that snapshot so I don't need to start fresh.

I had the same - ZFS across four drives with separate dataset and samba shares for each machine in my house. It would work and yes, I could rollback to a working snapshot. But it wasn't a set and forget system.
