We have just tested the subject question using ARCserve 2000 to attempt to recover a SYSTEM disk to its originally backed up functional status. So far it has failed badly. If anyone has done this could you please point us in the right direction. Our target system are 1. Compaq ML370, 2. Gateway 4200. Both are Windows 2000. The ARCserver Server is a Gateway 4200, Windows 2000 with ARCserve 2000.
