Result

If a network error occurs while an Exchange mailbox backup or archive job is running, the job will resume at the same folder and the same message in the mailbox that was being processed when the job was interrupted by the network error.

Configuring the Backup Mode

Answer the following questions to determine the method:

• How much data do you want to backup?

• Do you want to stub data to reclaim space on primary storage?

Choose the method that best matches your objectives:

• Method 1: Backup Mode

  Backup mode allows you to protect all content within the mailboxes and does not reclaim space on primary storage.

• Method 2: Backup with Selective Stubbing Mode

  Backup with selective stubbing mode allows you protect all content within the mailboxes and also archive based on stubbing rules. Stubbing rules allows you to reclaim space on primary storage.

• Method 3: Archive Mode

  Archive mode allows you to protect the mailbox content that meets the pre-defined stubbing rules. This option allows you to aggressively reclaim space on primary storage.

Backup Mode

In this mode the data on the primary storage (mailbox) remains intact and a copy of the data is created on the media. This mode is recommended if:

• You are primarily looking for the ability to perform granular data recoveries.

• You want to restore an entire mailbox to a point-in-time, but you do not want to do it from a database backup.

• You want to content index your Exchange data so that full mailboxes will be searchable for end users and the compliance officers.

• From the CommCell Browser, expand Client Computers > client > agent.

• Right-click defaultBackupSet, and then click All Tasks > New Subclient.

  The Subclient Properties dialog box appears.

        Ensure that you select a library attached to a MediaAgent operating in the current release.

     4. From the MediaAgent list, click the name of a MediaAgent that will be used to create the primary copy and then click Next.

     5. For the device streams and the retention criteria information, click Next to accept default values.

     6. Select Yes to enable deduplication for the primary copy.

     7. From the MediaAgent list, click the name of the MediaAgent that will be used to host the Deduplication database (DDB).
