As an Oracle DBA, I love love love snapmirror. a backup solution that anyone could implement and use to save their butt when they are trying to safely manage a 30 TByte backup.
Every recovery I have performed with snapshot'd files, was simply a "warm recovery" and very easy to oversee.

Has anyone explained or showed this person a write-up on WAFL and NetApp's implementation of RAID-4 and now RAID-DP? ...how NetApp's version does not have a "hot" parity disk as all disks are excersized about the same? ...how RAID-DP is superior to RAID 1+0 and in an edge case is even better (if you loose the same disk in both plexs of a RAID 1, you have total data loss...you can loose any two disks with RAID-DP and loose nothing) ...how RAID-DP has very little overhead compared to NetApp's RAID-4? ...how NetApp's RAID-4 is faster than most hardware RAID arrays?
I could go on, and on, an on....(ask others that know me...plus 10 years at netapp helped)
