WD5000AAKS - Mirrored Backup; RAID help

post #1 of 6
Thread Starter 
Hi.

So, I have a WD5000AAKS that has a lot of very important data on it, and it occured to me I have no backup.

Now, I know hardly anything about RAID, apart from RAID0, but still, not very much.

What RAID array would I have to use to have a mirrored backup so it'd just copy it whenever it adds new data/weekly or whatever, and just be an exact copy backup of the other drive? Would I need a RAID card, or could I use onboard RAID?

Any help?

RAID1 is a mirror array, but if you're just wanting to back things up I'd suggest just running a scheduled backup to an external drive.

RAID1 will give you better read performance (particularly sustained) than just the one drive, though.

Thanks.

Now, as far as RAID0 goes (the only thing I know anything about, really), the drives have to be formatted before they can be RAID'd, I'm assuming (well, hoping) this isn't the case with RAID1?

Certainly for all of the controllers I've used, you can form a raid1 array with, say, 2x500gb drives, one with the OS on, and one empty one.

The controller should automatically mirror the OS hard drive onto the empty hard drive when placed in the array.

Yes. And you need to make sure to Enable the RAID in your BIOS as well as have the Intel Rapid Storage Technology and Intel Storage Matrix drivers installed.
