How many times does it have to be said? Mirroring is NOT a backup strategy!
The number of times I've seen some sysadmin(s) base their entire organization on this faulty premise is absurd. Mostly it's because they have decided that RAID 1 or RAID 5 should be a decent "backup" strategy, but then there are those who believe mirroring systems is how to do backups.
They never, ever, take into consideration what happens when something corrupts/is deleted/is compromised. Without a way of going back in time (i.e. an actual backup) they are forever stuffed.
Sysadmins: MIRRORING IS NOT A BACKUP SOLUTION. STOP DOING THIS!!!
