Microsoft Exchange Local Mailbox Backup

  • This article is for Windows only

Carbonite Safe Server Backup (CSSB) supports backup of Exchange Local Mailboxes. CSSB supports Full and Incremental backups of Exchange Mailboxes. Differential backups are not supported. An Exchange Local Mailbox backup allows users to select one or more mailboxes from a local Exchange server for backup and restore, including an individual mailbox.

To configure Exchange Local Mailbox backups, create a new backup set and choose Exchange Mailbox Level Backup from the list of backup types. An Exchange Local Mailbox backup is intended to supplement an Exchange Database backup; not replace it. Transaction logs are only purged as part of an Exchange Database backup, which is also superior for disaster recovery purposes. Perform both an Exchange Local Mailbox backup and an Exchange Database backup for the best results.

Exchange Local Mailbox backups have the following properties:

  • Once user credentials are supplied, CSSB will automatically discover and display all available mailboxes.
  • Users may select all mailboxes or individual mailboxes for backup and restore.
  • Emails, Calendars, Contacts, Contact Groups, and Tasks will be backed up.
    • Attendees and attachments are not included in Calendar backups.
  • Items in the Junk folder will not be backed up.
  • Items in Resource mailboxes will not be backed up.
  • Items in Equipment mailboxes will not be backed up.
  • Items in Public Contact Groups will not be backed up.
  • New mailboxes will be automatically added to the next full backup if all mailboxes are selected. New Mailboxes will not appear in incremental backups until the full backup is complete.
  • Mailboxes that are removed from Exchange will be automatically removed from the backup if all mailboxes are selected.
  • Mailboxes are not automatically added or removed from the backup if individual mailboxes are selected.
  • Transaction logs are not purged as part of an Exchange Local Mailbox backup. Add an Exchange Database backup set to manage the Exchange transaction logs.

Requirements for Backing Up Microsoft Exchange Local Mailboxes

The following requirements must be met for Exchange Local Mailbox backups to function:

  • CSSB will attempt to use Exchange Autodiscovery to detect and connect to the Exchange server.
    • Autodiscovery must be configured and accessible from the system for automatic detection of your Exchange server.
      • Microsoft provides a free tool to test Autodiscovery at https://testconnectivity.microsoft.com. Select the option labelled Exchange ActiveSync.
      • CSSB attempts the Autodiscovery URL methods, which are included in the above test.
        • Only the URL test results are relevant. CSSB cannot connect to Exchange if the URL tests fail.
        • CSSB cannot connect to Autodiscover via the “HTTP redirect” or “DNS SRV redirect” methods.
    • If Autodiscovery fails, you will be prompted to enter the URL of your Exchange server.
    • Either Autodiscovery must work or you must supply the correct Exchange URL. CSSB cannot connect to Exchange without this information.
  • Only local Exchange servers are supported. To back up Exchange Online, use the Exchange Online Mailbox backup type instead.
  • The system must have Exchange 2010, 2013, 2016, or 2019 installed. Exchange 2007 and earlier are not supported.
  • The most recent service packs for Exchange and Windows must be installed.
    • For example, Exchange 2010 Service Pack 3 is available. Therefore Exchange 2010 running Service Pack 2 is not supported.
  • An administrator account must be specified within CSSB. The username must be in the User Principal Name (UPN) or email format, such as UserName@Domain. For example, Admin@company.com and username@company.onmicrosoft.com are both in the correct format.
    • For all Exchange versions, the Exchange Impersonation right must be granted to this administrator account. CSSB will attempt to add the Impersonation right automatically.
    • For Exchange 2013, sometimes the mailboxes will not be discovered and displayed after the account is specified. If this occurs, grant the eDiscovery permission to the administrator account.
