Specifying the backup items
If DS-Client can successfully log on to your Microsoft Office 365 domain, the Select Users & Services for backup screen appears and displays the users and folders for which you have permission to back up.
IMPORTANT: Although you can select multiple user accounts or site collections, we recommend limiting each backup set to one user account or one site collection for performance reasons. When you create Microsoft Office 365 backup sets using Cloud Management System in Windows DS-NOC, this limitation is enforced automatically.
NOTE: Do not select items for backup from both sources (Exchange and SharePoint) in the same Microsoft Office 365 backup set. Use a separate Microsoft Office 365 backup set for each backup source.
1. Select a user, folder, or site collection, and click Add or Exclude.
NOTE: You can exclude a folder or individual item only when its parent user, mailbox, or folder has already been added.
(Exchange Online only) To add or exclude individual items inside a folder:
a) Expand the user, select the folder, for example, Inbox, and click Items.
NOTE: The value displayed in the Size column reflects the size of the item on the source server in MIME format. This might differ from the size of the item in storage with full fidelity after it has been backed up.
b) Select individual email messages or entries that you want to specify, and click Add or Excluded as needed.
c) When you have added or excluded the required items, click Finish.
After you click Finish, the items that you have just added or excluded are displayed in the Backup Items Selected section.
2. When you have specified what you want to back up, click Next.
The Specify backup item options screen appears.
