Mirrored sets do protect against disk failure, but most of the time you'll find proper backups are better as most issues are more on the order of "oops" than "blowed up sir".
Perhaps mirrored sets with daily snapshots and a knowedge of how to mount snapshots as clones so that you can pull a copy of that file you deleted 3 days ago. :) If your especially paranoid a 3 way mirror set with copies set to 2. =) -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
