It usually can be done, but it depends on how it was backed up and on the RAID controller.
Unless you understand why you need to implement a RAID and how to back it up, you probably shouldn't do it. At a minimum you need to understand that RAID 0 improves transfer rates (this is why so many people use it), but a single hard disk failure causes the loss of all data on the RAID. RAID or not, you need to backup important data.
