It's a super-effective way of doing a limited number of generations of backups. (Small disadvantage is that your array is vulnerable during the rebuild cycle, but only new data would be at risk.) One drawback might be relative expense. If you're _serious_ about backup, and have a proper rotational backup schedule in mind, your cost of "media" (mirror disks used as backups) might be too high compared to more-conventional alternatives. If you're contemplating only two or three generations of snapshots, then you're not serious. Don't forget, too, that you'll need to be careful about the relative fragility of hard drives. As with all backups, you will want a plan to test the integrity of data.
