To confirm what is making the saveset large can you run nsrinfo on it
verbosely?  That will show what files are there, what their original
size was and how much size in the saveset they take up...

One possibility is compression - some data compresses in a negative way
- but usually only by about 5%

Another possibility is files linked to multiple filenames by hardlinks -
handled properly on unix clients, but not aware of anything similar on
NTFS - maybe newer versions  can do something like that and the
networker client doesn't support this yet..
