Right on all points. It's a calculated risk. If you have a hash collision, you will lose data undetected, and backups won't save you unless *you* are the backup. That is, if the good data, before it got corrupted by your system, happens to be saved somewhere else before it reached your system. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
