Just bought SP and intend to use the recovery CD to back up the VISTA C partition and immediately test with a restore. I don't want to screw it up. Are there any special considerations to keep in mind in using SP to make back-ups of partitions with FD-ISR snapshots? For instance, is it advisable to back up the whole partition including free space; is defragmentation recommended beforehand, etc.? Is it useful to exclude any folders / files? And any other suggestions?
