Backup of Exchange 2007 or other VSS backups fail when the source server has the Acronis VSS Provider installed

Problem

Backup of Exchange 2007 or other VSS backups fail when the source server has the Acronis VSS Provider installed

Error Message

AOFO: Initialization failure on: "". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS). V-79-10000-11235 - VSS Snapshot error. Microsoft Volume Shadow Copy Service (VSS) cannot communicate with the writers.

Final error: 0x80042318 - 0x80042318 (2147754776)

Solution

Issue occurs when the Acronis VSS provider is installed on the server.

Edit the backup job and select the AOFO option "Microsoft Volume Shadow Copy Service".  
Then select the drop down option of "System - Use Microsoft Software Shadow Copy Provider" to force the Microsoft VSS provider.


 

NOTE: This error can occur even if the AOFO option is not selected. This is because backing up the System State or the Shadow Copy Components will automatically engage VSS.
