Enabling Block-Level Backup for Exchange Databases

Applies to: Exchange 2010 or later

You must enable block-level backup at the subclient level before you can recover messages.

Before You Begin

Make sure that you have a sufficient amount of space for the index. For every 100 GB of data, you should have 30 MB of available space for the index.


  1. From the CommCell Browser, expand Client Computers > client > Exchange Database.
  2. Right-click subclient, and then click Properties.

    The Subclient Properties dialog box appears.

  3. Click the Advanced Options tab.
  4. In the Block-Level Backup Options area, select the Optimize for message level recovery check box.

    A message appears that tells you that the next backup will be converted to a full backup.

  5. Click OK to clear the message.
  6. Click OK.

What to Do Next

After you perform a block-level backup, you can recover messages without restoring the entire database.
