Creating a Mailbox Level Backup Set

Microsoft Exchange Mailbox Level (or brick-level) backups provide you with a way to archive your clients' mailbox data for long-term, granular restores.  Emails, contacts, and calendar items can be restored on an individual basis, or in bulk, to provide flexibility when reinstating a user's email.

Mailbox Level backup sets are best used as a data-archiving utility to keep a record of the emails sent and received (as well as contacts and calendars) over a long period of time.  Intronis do not recommend using Mailbox Level backups as a disaster recovery solution since restoring an entire information store via a Mailbox Level backup is much slower than restoring from an Information Store backup.



Mailbox Level backups are performed by a service account that uses Exchange Web Services to extract mail.  If you have not set up this user account already, you will need to do so in order to perform backups successfully.  Directions for doing this are here.

Additionally, there are a few special cases you should be aware of:

  • When backing up an Exchange 2007 instance with Mailbox Level backup, the backup software must be installed on a machine in the same domain as the Exchange server.  This limitation does not hold for Exchange 2010 and up.

  • If the Exchange server is running Windows Server 2008 (non-R2), you may need to manually install Powershell 2.0.


Creating a Mailbox Level Backup Set

  1. Log into the management portal and navigate to the computer account you want to add a Mailbox Level backup set to.

  2. Go to the Backup tab and click on the button next to Exchange Mailbox Level.

  3. A pop-up will appear prompting you for the EWS URL and the service account's username (in UPN form) and password.  If you do not know the EWS URL, you can find it by opening Exchange Management Shell and entering the following command:

    Get-WebServicesVirtualDirectory | Select name,*url* | fl

    We recommend you use the external URL but others may work.  Once entered, hit Confirm to validate the address and credentials.

  4. If the credentials you entered are accepted, you will be taken to the Select tab of the backup set editor.

    First, set the name of this new backup set by clicking on the name at the top or on the button next it.  Choose whether the backup set will store its backups Local Only, Online Only, or Online and Local.

    Note: 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, reference this article.

    Choose which mailboxes to back up by placing a check next to them and decide if new mailboxes will be included in the backup set by toggling the Automatically add newly created mailboxes to the backup set option at the bottom.

    When done, hit Next.

  5. newmailboxlevelsetup3.png Set a schedule for the backups by choosing a recurrence interval (minutes, hours, days or weeks) and either how often the backup will run or on which days the backup will run.  If you want to add more than one schedule, click the Add New button.

    If you choose a By Week recurrence interval, you can choose to let backups finish on their own or, if you uncheck the Allow to Finish box, forcibly cancel the backups at a given time.  If you choose the latter, any mail items backed up before the cancelation time will not be lost.

    Hit Next to proceed.

  6. On the Advanced tab, choose the temporary folder (will need 1-2 GB of free space) and whether "Deleted Items", "Spam", or "Junk Email" folder will be backed up.

    Click Next to see a summary of the backup set or hit Create Backup Set to finalize the backup set creation.
