Issue



A backup of Exchange on Windows Small Business Server 2003 completes successfully however the job log reports: V-79-57344-34110 - Note: Resource: "Microsoft Information Store" is not snappable. Attempting to back up directly from the source volume.

 


Error



V-79-57344-34110 - Note: Resource: "Microsoft Information Store" is not snappable. Attempting to back up directly from the source volume. 

Note: The backup of the Exchange Database will still complete successfully however it will not be a Snapshot backup and the above error will still show in the successful job log.

 


Cause



By default, the Setup program for Microsoft Windows Small Business Server 2003 turns off the Microsoft Exchange Server 2003 writer for the Volume Shadow Copy service. The Exchange 2003 writer may cause conflicts with the Backup utility (NTBackup.exe). However, you can manually turn on the Exchange writer for use with third-party backup software.

 


Solution



Option 1: Ignore the error in the job log

The error is reported because Windows rejected the snapshot request. The Information store is still backed up and recoverable.


Option 2: Disable the snapshot backup method and re-run the backup

1. Disable the Advanced Open File Option (AOFO) option within the backup job
2. Re-run the backup (The error will no longer appear in the job log)
 

Option 3: Enable the Exchange VSS writer to perform a snapshot backup of Exchange and re-run the backup

*Warning - It is important to know that a snapshot backup of Exchange does carry restore limitations. Please see  http://www.symantec.com/docs/HOWTO24087 for more information.
