About Creating a Mailbox Level Backup Set

  • Last updated on

With Exchange Mailbox Level backups, you can:

  • Use Exchange Web Services (EWS) that allows multi-threading.
  • Restore directly to a mail message (.msg) file or to an Outlook Personal Storage Table (.pst) file.
  • Run the software from any computer with web access so the agent does not need to be installed on the Exchange server.

Exchange Mailbox Level backups allow you to back up users' mailbox data for granular restores. Mailboxes, contacts, and even individual mail messages for a user can be restored on an individual basis, or in bulk, to provide flexibility in the choices you have 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. It is not recommend using mailbox level backups as a disaster recovery method because restoring an entire information store via a Mailbox Level backup is much slower than from an Information Store backup.

The backup agent supports backing up mailboxes from a single domain or multiple domains using an existing sub-account.

Prerequisites


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 need to do so as to perform backups successfully. Directions for doing this are here.
