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. This guide will show you how to set up an Exchange Information Store backup set.
Log into the management portal and go to the computer account you want to add the backup set to.
Click on the Backup tab and hit the button next to Exchange Information Store.
First, set the name of this new backup set by clicking on the name at the top or on the button next it. Then, select whether you want the new backup set to 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.
Any mailbox databases present on the server the Backup Agent is installed on should be detected automatically and listed in the Current Selection window. Choose the one you want to back up and click Next.
Set a schedule for the backups by choosing which days the backup will run, and what method (full or incremental) the backup will use – more information about that distinction is here.
By default, one full backup is scheduled. You can have more than one full backup scheduled but may not have fewer than one full backup. If you want to add more than one schedule, click the Add New button.
Hit Next to proceed.
On the Retention tab, adjust the archiving rule to your needs or check the box for Enable Advanced Archiving to use an advanced archiving rule instead of the default one. Information about advanced archiving rules is found here.
When finished setting an archiving rule, click Next.
Finally, specify a temporary folder location for the backup set. For Exchange Information Store backups, we recommend you have temporary space equal to or greater than the size of the mailbox database you plan to back up. This requirement pertains to the full backups, so expect incremental backups to use less temporary space.
When done, click Next to view a summary of the backup set or hit Create Backup Set at the bottom to finish making the backup set.
