Norton was notorious for using undocumented hooks into products. So, likely to break any time you made some unexpected change (upgrade) to your system.
For a ghost replacement, clonezilla works fine. Or, the partimag, etc. tools contained within. For me, the advantage is that I can examine the code and figure out how to make it do what I want/need "when/if things go wonky". COTS solutions seem to go to great pains not to document ANYTHING either intentionally (security by obscurity) or out of economy (why spend money documenting something that folks shouldn't NEED to understand... and then have to *support* that particular implementation).
[I was a strong advocate of Ventura Publisher (when owned by Xerox). Once Corel purchased it and started obscuring document details (efficiency?), it left me (and my documents) at the mercy of their "latest implementation"; I could no longer go into a raw document and "fix" things that their software couldn't.]
