IMHO, snapshots are not a replacement for backups. Backups should definitely reside outside the system, so that if you lose your entire array, SAN, controller, etc., you can recover somewhere else. Snapshots, on the other hand, give you the ability to quickly recover to a point in time when something not-so-catastrophic happens - like a user deletes a file, an O/S update fails and hoses your system, etc. - without going to a backup system. Snapshots are nice, but they're no replacement for backups. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
