I have Norton Ghost 9 in my main OS hard drive. I also have two external identical Lacie hard drives. I used Norton Ghost to create a backup (base with incremental) of one external hard drive to the other external drive. So now I have two backup files located in the external hard drive named "DELL-INK8SUN8DHB.sv2i" (Symantec Recovery Disk file, 3kb) and "L_Drive001.v2i" (Symantec Image file, 381,039,488kb).
Then I did a clean Windows install in a new drive and installed Norton Ghost 9 there. Now I want to do an incremental backup, but the backup job is not listed, how can I retrieve the backup job from the old drive so to do an incremental backup in the new drive? Thanks.
