To dump the contents of a save set, use mminfo to get the nsavetime of the save set you're looking at.. For example: mminfo -q "ssid=xxxxxxxx" -r "nsavetime"
Next, take the nsavetime and run nsrinfo against it.
nsrinfo -t <nsavetime> <clientname>
You can dump the contents to a file and then compare to what's currently there.
Good luck!!!!
