Hello ,
Yes I have created 2 profles 1 is desktop & 2 is laptop profile.when 500 users are connected to this 2 profiles.In this case when 2 users login in same computer (i.e two different users) DLO backuped all the data for both the users as per the proflie so the duplication data will be created on DLO Server.
My Desktop profiles settings are follows
Desktop Users -:Backup Selection ( C,D,E Drive -include files *.doc,*.xls,*.ppt,*.nsf)
