I'm currently running a Raid 0 configuration and wondering if I could switch it to a Raid 1 config without losing any data currently on the 2 drives. Is there any software that will allow it to happen? Do I have to create a complete image of the raid 0; reconfigure and re-format and then restore the image? I currently have 2, 640 gig drives running Raid 0. About 300 gig is currently stored on the array. Would the back-up image be 300 gig or 1.2 terrabytes.
Thanks.

I'm afraid you would have to back up and restore or create a new RAID1 array using two different disks and copy everything to them.
As you'd backup at the filesystem level, not the block device level, you'd need 300GB of storage.
