IMHO using all three is too much. you can pick one, and combine that with other (non-snapshot) backup strategy. vmware snapshot is good because it also stores memory state, but it also uses more space. What I recommend you to do in your current setup: - check whether your application can survive an unclean shutdown/power outage (it should). If not, then you have to do application-specific backup. - do zfs snapshot plus send/receive - add regular tape backup if necessary, although it might not need to be as frequent (you already plan this) - regulary excercise restoring from backups, to make sure your backup system works. -- Fajar _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
