RAID 1 Array Creation?

I have installed many RAID zero arrays from scratch and also a RAID 1 array from scratch so am knowledgeable on how to to this. However, if I currently have a SATA drive in a nVidia nForce motherboard and want to add a second drive in a RAID 1 format to have completely redundant backup, is it as simple as performing this from the motherboard BIOS RAID utilities and duping the existing drive? If that would work than I can give the gentleman a completely secure and simple method of backup. I haven't tried it yet as I am a bit leery of messing with his existing drive until I am absolutely certain I can do this safely first. Thanks for any help.

RAID-1 shouldn't be used for backup but for minimizing downtime; any data corrupted by user error, malware, whatever will be saved identically on the other drive. You should also consider offering an external drive and scheduled incremental backup plan.

However, I do think that the motherboard utility should allow you to mirror the current array onto another drive.

BIOS utility should work fine for that. But as Rogue said, RAID 1 is not meant to be used as sole backup solution.
Maybe backup the drive before you attempt RAID creation? You never know what could go wrong. This is the least I would do when messing with someone else's data.

Just hassles & expense for what gain? Maybe a few milliseconds faster read/write...why bother? Caches are big enough now that the tiny extra RAID speed isn't worth it.

At home, I'd rather use my extra disks for backup than put them into a RAID array.

Yeah RAID0 is useless for almost all home users.
