Then the next snapshot always begins immediately after the last one finished. Why not dispense with cron and have the script enter a never-ending loop to do the snapshot?

I have noticed that it is pokey. NFS data should not be written without commit unless the client is willing to roll-back to the uncommitted bit when the server crashes.

Supposedly you can just do manual synchronizations periodically instead of real-time, but then what benefit does AVS have over ZFS snapshots... It would just add a lot of complexity. We had a few Sun engineers come to our site, and dissuaded us from AVS for those exact reasong (though Sun's sales people said AVS was the best thing since sliced bread) Sturban,
