Solution



Microsoft Virtual Server 2005 R2 SP1 Protection on Microsoft Windows 2003:

Microsoft Virtual Server data is now supported in Backup Exec for Windows 12.x using Microsoft Volume Shadow Copy Server (VSS).  Backup Exec takes snapshots of the Virtual Server HOST while applications and services run.  The host in turn takes snapshots of all the guest virtual machines it contains.  Microsoft Virtual Server data and guest machines are selected under the HOST servers Shadow Copy Components - User data selection.

(FIGURE 1)
 
To properly protect an Exchange server, install the Backup Exec Remote Agent (RAWS) on the guest.  After the Backup Exec Remote Agent is installed, only use it to backup/restore the guest directly.  The Backup Exec media server must have the Exchange Agent installed.

Workaround:

Prior to the Exchange guest backup have a script run or manually shutdown the Exchange services. For additional information please see Microsoft documentation for recommended Offline Backup and Restore Procedures for Exchange.
