Hi Richard, Actually, reading your reply has made me realise I was overlooking something when I talked about tar, star, etc... How do you backup a ZFS volume? That's something traditional tools can't do. Are snapshots the only way to create a backup or archive of those? Personally I'm qui

I agree, mailing that to all Sun customers is something I think is likely to turn around and bite you. A lot of people are now going to use that to archive their data, and some of them are not going to be happy when months or years down the line they try to restore it and find that the 'zfs rec

Hi Mike, I reviewed this doc and the only issue I have with it now is that uses /var/tmp an an example of storing snapshots in "long-term storage" elsewhere. For short-term storage, storing a snapshot as a file is an acceptable solution as long as you verify that the snapshots as files are valid
