Gearrion

I would keep the ghost image on a external drive, and use the third drive for a RAID 5 instead of a RAID 1. If you are going to Image the system setup a schedule with software Like acronis to make a differential backups every twelve hours on the third drive, and then make a RAID 0 for the other two disk. Disc 1 - non raid C: Windows XP D: Documents and Settings Disc 2 and Disc 3 - Raid 0 E: Paging File F: Program Files G: Data Files ( My documents, My pictures, My music) H: Downloads Disc 4- non Raid I: ACRONIS with differential backups Therefor the fault tolerance would be only twelve hours. If the drive is large enough you can make it every four hours. If it is really Big make it every other hour. It runs in the background and does not hinder performance. Personally I backup only once a month.
