My current setup is daily backups and RAID 0 for speed, not redundancy. However, if at one point of time I afforded, I will use RAID 5, and backups like you describe. The best way I found, is to do daily backups in directories named SUN, MON .... except for one day in the week, where the backup directory is named by the date. So by that way one can go back a week, then weekly as large as the backup hard drive can take. And best, if the backup script unmounts the backup hard drive when done. You’re right, I agree with you.

If your database gets corrupted or trashed for any reason (programming error, hacker, admin mistake...), RAID won't help you at all. Backup will. Backup ALWAYS. RAID is an add-on.
