If you care enough to do backups, at least care enough to be able to restore. For my home backups, I use portable drives with copies=2 or 3 and compression enabled. I don't fool with incrementals, but many people do. The failure mode I'm worried about is decay, as the drives will be off most of the time. The copies feature works well for this failure mode. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
