ZFS snapshots can be a fast and easy way to perform backups.

Napp-IT has a commercial (Pro) module available that performs ZFS snapshots and sends them to another ZFS server.

Snapshots are automatically mounted under /$MOUNTPOINT/.zfs/snapshot/$SNAPSHOTNAME.

You could also clone the snapshot if you don't want to muck with .zfs, copy out your files/folders that need recovering, then destroy the clone.
