There's an autosnapshot service available, but AFAICS, it doesn't have any way to run pre- or post-jobs. What I'd do is just run the rsync jobs (preferably one dataset per server), and then snapshot manually from the script. For doing automatic snapshotting on S10, I wrote the script at http://karlsbakk.net/ZFS/zfs-snapshot.sh - while that works, it's got a logical bug, the daily snapshots are named by name of last day, meant to be run just after midnight, whereas the other snaps take the current, say month or time, as the name. Since we have this in production, I've simply informed our users, since changing it now will mess up the structure, and we won't be using s10 on our fileservers for long anyway.

Vennlige hilsener / Best regards

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med fremmed opprinnelse. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
