I'm not sure what you are asking, Henry.
Do you mean that you are unable to access the backup configuration?
Your Windows User ID must be an administrator.
Open OneCare, click Change Settings
Backup Tab.
Change Settings from lower right.
Select your PC name to view and change the options.
Select Centralized Backup if you wish to change the settings for all PCs in your Circle, using Centralized backup.
