1. Add clients following these steps:

  • Exchange 2010 backup requires creating two clients on the CFA: one 64-bit client to backup the Exchange database files with the VSS Exchange writer, and one 32-bit client to backup the email at the mailbox and message level. The two clients must communicate with the Exchange server over different ports. Follow these instructions:
    1. Add one client (64 Bit) with a name like Exch10Data. Create the client selecting MS Windows/x64 as the Client OS. The database backup is done exclusively with VSS capabilities, so you will not have to install the plugin.
      * If you are running 3.5 RevOS version, make sure the "Enable/Override" option is selected in the client file set. If this is not enabled, the databases will not be backed up.
    2. Add another client (32 Bit) with a name like Exch10Mailbox. Create this client selecting MS Windows as the client OS. Edit this client to use TCP port 9202. Note: if you do not change the port, you may see error messages like ""log failed with error (1314): A required privilege is not held by the client."

2. To insure the database backup will occur:

  • In the CFA UI, create the 64bit client (named something like Exch10Data. In Clients > Edit you'll then need to edit the fileset (this is the icon that looks like a pencil, next to 'File Set'). Make sure that 'VSS' is selected as well as 'Include Writers'. Select 'Override Plugins' and then choose the Exchange Database below that.
    • Please make sure that you do not have any other backup program running when the CFA starts a backup. They could conflict over VSS access causing one or both backups to fail.
    • Also, do not use another program to backup exchange databases. The VSS writer will not distinguish between the backup programs, so the incremental or differential backup from one program could depend on incrementals, differentails and fulls run by the other. Becuase of this, neither system will have everything needed to restore anything other than full backups.

3. Install the MAPI client libraries.

  • MAPI client libraries are not included in the base installation of Exchange 2010. To enable the message level backups you will be required to download and install the Microsoft file ExchangeMapiCdo.exe.
  • Restart the Microsoft Exchange Information Store service after installing ExchangeMapiCdo.

4. Install the client software.

  • The client software can be downloaded from the Clients > Software tab.
  • Be sure to install the 64-bit agent for the Exch10Data client AND the 32-bit agent for the Exch10Mailbox client.

5. Configure the 32-bit agent using "Configure Backup" (not 64-bit). This is the agent that will run the mailbox level backup.

  • Confirm that VSS is disabled (do not use) for this client. Edit the client file set (Clients > Edit > Pencil Button next to FileSet) and make sure the VSS option is not checked.
  • Be sure that systemstate is disabled, via the RVXConfig and/or fileset, for this client.
  • If you are running 3.5 RevOS version, make sure the "Enable/Override" option is selected in the client file set. If this is not enabled, the mailboxes will not be backed up.
  • Because of Exchange overhead (MAPI), the mailbox level backup will be considerably slower than the database or flat file backup.
    • Any flat file or system writer backups should be configured on the database client to maximize backup speeds
  • Note: this user will need to have a mailbox, the mailbox cannot be hidden, and you need to be able to send and receive mail from this mailbox to allow mailbox level backups to succeed.
  • Where DOMAIN=your domain, below:
    1. Create a domain user (such as "RvxBackup") with a User Mailbox (easiest using Exchange Management Console).
    2. Add the user to the group on the Exchange server: BUILTIN\Administrators
      • My Computer > Manage > Local Users and Groups > Groups > Administrators > Add to Group... > DOMAIN\RvxBackup
    3. On the Exchange server > Backup Agent (the 32-bit client with unqualified name, not 64-bit) > Configure Backup > Service Control > Stop
    4. Run Service As: > (x) Other Account: "DOMAIN\RvxBackup" > Password: * > Confirm Password: * > Start

Other Notes and Recommendations.

  • Do not install Outlook on the Exchange Server. Installing Outlook with break the MAPI we depend on for mailbox backups.
  • The clients may be started from either the RVXConfig tool or the Services window.
  • Verify that your Exchange clients have a green check mark in the Client > Summary tab. You may test a new client by running a manual backup.
    • The MBXBackup is performed at the beginning, you may see this working by viewing the properties of a running job.
  • We strongly encourage the use of a Weekly schedule for an Exchange client. Please do not run a schedule that mixes differential and incremental backups.
  • Though allowed, we do not recommend truncating the logs after incremental or differential backups. By default we truncate the logs only after a full backup.
  • To verify that Exchange has been backed up, either browse the job(s) in the Job History or browse the client from the Client Summary. You may see the default C:/ directory and also a new EXCHANGE:/ directory. Both directories can be browsed.

Note: If you make any changes to the client configuration via the RVXConfig window while the client is running, you must restart the client before changes take effect.


Error messages and Resolutions:

  • ARNIE-FileIO JobId 292: MBXBackup Fatal: MAPIInitialize failed : MAPI_E_CALL_FAILED
    • Install the ExchangeMapiCdo file.

(in MAPI 1.0) : This information service is not installed on your computer. To install it, use the Mail And Fax icon in the Control Panel. : MAPI_E_NOT_FOUND

  • Try just restarting the agent. (May be needed after installing ExchangeMapiCdo)

then to enable it:

  • Navigate to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
  • Modify the "Disable Exchange Writer" registry key to a value of 0.
  • Restart the "Microsoft Exchange Information Store" service.
  • VSSadmin list writers should now display the writer correctly.
