This seems like a good plan to me.  Approaches which result in a 
"carbon copy" of a zone don't work so well when the "carbon copy" is 
not a good match for the host system when it is restored.

A backup approach which also serves as documentation for later about 
what was changed is very useful.

It does seem like IPS should be able to produce the list of files 
provided by the OS, as well as any files which were subsequently 
changed, since it already knows how to not overwrite files which were 
changed.
