Sorry, I don't know what "SAM-QFS" or "DMAPI HSM with ADM" are. Looking at the web page above, this doesn't sound like a simple replacement for ufsdump suitable for desktop use. Surely there must be something simpler? Some way to integrate zfs snapshots with the ability to write to and manage multiple tapes? (No, I haven't tried star yet. I was hoping for something that comes as a part of Solaris. Plus, star doesn't seem to know anything about zfs snapshots.) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
