Cons:
Issue if you remove it from the startup folder it has to reconnect to something, and cannot preform an incremental backup
Issues with backing up to disk
It's a Symantec product! =p
Pros:
Feature Rich
Considered Reliable? (http://ghost.radified.com/)
Nice options (for networks [backup to disk, backup to network, remote management])
Works Fast (some speculation, incremental after full restore and defrag was half the size 15gigs, of the full restore, no files were opened/added/changed)


Just from a glance and reading what I have I would say while Norton looks promiseing I am a little gun shy when it comes to their products, too many problems, So for my personal use I would probably use somethign like Macrium Reflect because it has the features I need without  the complications I don't.
