This requirement has been submitted here before. There is no easy way to delete 
a single backup version. You can only backup the new version a couple of time 
(the amount have set in the copy group properties, 'number of versions to 
keep') but that's a lot of work for just one file.

ADSM doesn't backup network shares by default, however you can select them 
through the GUI. I expect you can back them up by explicitly including them in 
your DSM.OPT file, but I haven't tried it yet.
