Database Level Restore Sets

When you back up an Exchange Server 2003 or 2007 server, each storage group you selected to back up is saved on media as an individual session. When you back up an Exchange Server 2010/2013 server, each database you selected to back up is saved on media as an individual session. To restore an Exchange server, you must restore all of the sessions that, when combined, completely restore the backed up object. These sessions are called your restore set.

The number of sessions in your restore set depends on the backup methods you used:

• If you backed up using only the full backup method, your restore set includes only this full session.
• If you backed up using both full and incremental backups, your restore set includes your full session and at least one, but up to as many incremental sessions as you want to include. For example, in the following backup scenario, your restore set can be full and incremental 1, full and incremental 1 and 2, full and incremental 1, 2, and 3, or full and incremental 1, 2, 3, and 4:

  

• If you backed up using both full and differential backups, your restore set includes your full session and one differential session. For example, in the following backup scenario, your restore set can be full and differential 1, full and differential 2, full and differential 3, or full and differential 4:

  

After you determine your restore set, the entire set must be selected when you submit the restore job. When using the Restore by Tree method, select the last incremental or differential session in your restore set and the agent will automatically include the full session for you.

To select restore sets in the Restore Manager

1. From the Arcserve Backup Home Page, select the Restore Manager from the Quick Start menu.
2. When the Restore Manager opens, select Restore by Tree in the drop-down box below the Source tab.
3. Expand the server that has the Information Store that you backed up, select the Information Store, Storage Group, or database object, and select a Recovery Point session. Choose a backup date and then select a Recovery Point for that date. If your restore set includes incremental or differential backups, select the last incremental or differential backup in the set and the agent will automatically include the full backup for you.
4. Set your restore options, specify a destination, and submit the job.

   Note: If you use Restore by Session rather than Restore by Tree, you must repeat Steps 1 to 4 for each session in your restore set.
