“Exchange Trusted Subsystem” must have Read/Write permissions to the working directory.
The working location defaults to Product “temp” directory.
Supported Exchange Server versions
Exchange Server 2010 SP1 is the minimum supported version.
Mailbox Permissions
An Active Directory User or a Group must be granted “Mailbox Import Export” role. Typically,
running as Administrator, the product service already has necessary permissions for the mailboxes.
To manually grant this role, execute the following cmdlet in the Exchange Management Shell:
New-ManagementRoleAssignment –Role “Mailbox Import Export” –User
Domain\User
Where, Domain is the Active Directory Domain name and User is the account granted permissions.
To grant necessary permissions to a group use:
New-ManagementRoleAssignment -Role "Mailbox Import Export" -Name "Import
Export Mailbox Admins" -SecurityGroup "Mailbox Support"
PowerShell Access
If the product service is running under an account that does not have access to PowerShell, you
need to specify a valid account with permission to execute PowerShell cmdlets. Typically, running
as the default, Local System account, the product service automatically has access to PowerShell.
Best Practices and Performance Considerations
You should perform frequent incremental backups of Exchange mailboxes in addition to full backups.
Daily incremental backups followed by weekly full backups will reduce the recovery time and the
backup size. Incremental backups also enable you to conveniently specify a restore window to
recover mailbox items.
Consider the case where you wish to recover a few deleted messages from your inbox after the
retention period has expired on the Exchange Server. If you know the date the original messages
were sent or received, you can recover them within seconds of running the mailbox restore.
However, if you only had full backups of the mailbox, you would be forced to restore the entire
mailbox, whose size could run to several gigabytes, requiring a much longer restore time.
Backup performance is dependent on a number of factors including but not limited to:
1. Mailboxes in the Exchange Sever
2. Count of mail items in each mailbox
3. Type of Backup (Full, Copy, Differential, Incremental)
4. Hardware powering the Exchange Server deployment
There are no special requirements to improve backup performance of the Mailbox Agent. However,
backup performance can be optimized by selecting only essential mailboxes from the Agent and
performing incremental backups on a regular basis.
