Creating an Exchange Information Store Backup Set

  • Last updated on

Having an Exchange Information Store backup is an important part of a disaster-recovery plan for any server hosting Exchange mail services.

An Exchange Information Store backup allows you to restore an entire Exchange database back into production as well as to a recovery group for the purpose of restoring individual mailboxes.


To create an Exchange Information Store backup, perform the following steps.

  1. Log into the management portal and navigate to the Computer page. See Navigating to the Computer Page for instructions.
    The Computer page is displayed.

  3. In the Backup Type pane, click Exchange Information Store.
    The Select page is displayed.

    Depending how you have the Backup Agent and computer account configured, you may only see one or two of the storage type options. For more information on which types should be available, see Choosing Where to Store Backups.

    Any mailbox databases present on the server the Backup Agent is installed on should be detected automatically and listed in the Current Selection window.

  4. Click the Backup Name to provide a new name for the backup set or accept the default. See Changing Backup Set Names.

  5. At the Select Storage Location section, click one of the following radio button options:
    Note: This procedure applies to all options. See Backup Options for more information.

    Local Only (Local Vault must be enabled, and a local subscription is required. Data is not backed up to the cloud.)
    Online Only (An enabled Local Vault disables this option.)
    Online and Local (Local Vault must be enabled.)

  6. At the Current Selection pane, select the storage group to be backed up.
    Clicking the arrow image2021-9-23 14:14:55.png at the right of the items displays more storage groups.

  7. The storage group’s name and size are displayed at the far right.

  9. Accept or edit the default schedule. See Adding a New Daily or Weekly Schedule for more information.
    Multiple weekly schedules are permitted (if they do not overlap).
    The Allow to Finish check box is always selected and grayed out.

  10. Select a backup method radio button, Incremental or Full.
    : If you select Full, every backup runs a full.
    If you choose Incremental, the first backup is a full and the subsequent backups are incremental.

  11. After setting the schedule, click Next.
    The Retention page is displayed.

  12. Select the number of versions you wish to archive.
    : The default retention is kept 4 weeks and no fewer than 4 versions.

  13. Optionally, select the Enable Advanced Archiving check box. For Advanced Archiving information, see Archiving Rules.
    The Advanced Archiving fields are displayed.

    Example: The setting of a daily backup kept for 30 days and no fewer than 10 versions mean that 30 versions are kept. However, a setting of once a week means that after 10 weeks, 10 versions are kept.

  14. Make your selections, click Save Rule, and then click Next.
    The Advanced page is displayed.

    image2021-9-23 14:30:34.png
    : You must specify a temporary folder located on a disk with enough space.

  15. At the Temporary Folder field, accept the default, type a new path, or click the Browse button to locate the temporary folder that is used in backing up. See Browsing to a Folder.

  16. After making your selections, click Next.
    The Summary page is displayed.

    image2021-9-23 14:31:52.png

  17. At the Summary page, verify your backup selections, and then click Create Backup Set.
    If you did not change the default backup set name, a confirmation pop-up is displayed after clicking the Create Backup Set button, as shown in the example below.

    image2021-9-23 14:33:21.png
    This feature allows you to create a unique name for the backup set. If you already changed the default backup set name, the pop-up is not displayed. See Changing Backup Set Names.
    The Backup Selections page is displayed with the latest backup set.

  18. To manually run the backup, see Manual Backups.
