[QUOTE="rman, post: 7516, member: 23"] Even with the ~870 MBs of new data nightly, an incremental backup is the cheapest solution. Basically all raid does is help increase the system up time. In that if a disk fails, you switch over to mirrored disk. Since you don't plan to mirror your system disk, which is the normal case, you are not gaining much by using mirror only on the data disk. It would be better to mirror both disks if you are going to do this. Just trying to help you think this through, why do you only want to mirror the data disk and not include the system disk? The reason I ask, because it does not appear that you are creating a fail over system. It looks like you can afford some down time. Most companies that use any type of raid are trying to reduce the mean time between failures (MTBF). [/QUOTE]
