As others have said, ZFS works a little differently to a standard file system. Basically remember that you don't get anything for free. I think of snapshots as an efficient way of storing backups. You have a copy of all your data, but it's still a copy that's stored on the disk.
The real benefit is when you realise how little data changes. At work we have around 500GB of live data, but our rate of change is only around 50GB per year. That means a 1TB drive can store all our live data, and potentially around ten years worth of snapshot backups too. The biggest downside to snapshots is that you can't easily free up space. So long as you are aware of that, and plan accordingly, the benefits are well worth it. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
