DS-Operator F1 Help for GUI (Context-Sensitive) : Select Storage Group
 
Select Storage Group
Use this dialog box to select from the defined Storage Group(s). If none are defined, a default group appears. Data from the customer or DS-Client will be sent to this Storage Group’s Extensible Storage Location(s).
NOTE:  If you change a Storage Group after backups have been performed, it will not affect that data. Only new backup data will go to the new Storage Group.
