RAID is not a backup, its a redundancy dependent on a controller remaining functional.
If you had a Drobo in RAID-1, you could not remove a drive and read it independently. Or any other RAID box for that matter. A backup is identical copies stored separately and in different locations.
If you are referring to my post, please read it again. You apperently missed about 85% of what it said.
DROBO is not a real RAID 1 controller either fyi. DROBO itself goes out of it's way to clarify this.
DROBO, like my own post, also goes out of it's way to state that it's "BeyondRAID" technology "protects data against a hard disk crash, yet is simple enough for anyone to use. As long as you have more than a single disk in Drobo, all data on Drobo is safe no matter which hard disk fails."
FYI, I donlt know if what yousay about needing a DROBO controller to read the data off half of RAID 1 is true, maybe it is hard to get that data back, maybe not. If so, unlike DROBO's proprietary "BeyondRAID" Most real RAID 1 arrays = two hard drives that are fully readable on any most controller with the correct software. If one fails, the other is not only readable on the controller that it is installed, no loss in productivity, but if for some reson you lose the controller, you can put that still working drive in a USB removable etc, and pull the data off on another system.
All that said, I concur that RAID is not a backup!
As I stated in my initial post re: RAID, I'll repeat;
IF the "wedding pro" had transferred the cards to a RAID 1 array, even if the catastrophe occurred in the moments/hours/days before a "real back up" had been done, the remaining hard drive in the RAID 1 array would have kept the data for a future back up.
Anyway, we are on the same page re back up. I just think you may have misread my point on where the actual advantage of RAID 1 lies. I've had RAID 1 save my bacon more than once, and it's kept me working when I would have had to stop dead in my tracks on a few occasions as well. Combined with a good back up and off site, it is one of the most cost effective ways to keep you working when hard drive fails.
