I am unable to backup my Exchange database with Retrospect. I am able to successfully backup the database with Windows Server backup. When I start the process I receive the following events in the event log:
1. Exchange VSS Writer (instance b6fd1f2b-d4f8-4379-8789-308d71ed6355) has prepared for backup successfully.
2. Information Store (4924) Shadow copy instance 18 starting. This will be a Full shadow copy.
3. Exchange VSS Writer (instance 18) has successfully prepared the database engine for a full or copy backup of database 'Mailbox Database 0910901174'.
4. Exchange VSS Writer (instance b6fd1f2b-d4f8-4379-8789-308d71ed6355:18) failed with error code -2147467259 when checking volume dependencies for storage group '6c4daad9-1ef6-4b01-abe0-f6258087011c' in preparation for backup.
5. Information Store (4924) Shadow copy instance 18 aborted.
6. Exchange VSS Writer (instance b6fd1f2b-d4f8-4379-8789-308d71ed6355:18) failed with error code 1006 when preparing for Snapshot.
Note that on the fourth event the details tabs shows: CVssIExchWriter:FCheckInstanceVolumeDependencies: Log file path is not affected by the snap..
I have added my backup account and the Network Service to the VSSAccessControl. I have also granted Network Services COM+ Local access and activation at the computer level to attempt to resolve a VSS 8194 error that I was previously receiving. The error details for that error were:
0x80070005, Access is denied.
Operation: Gathering Writer Data Context: Writer Class Id: {e8132975-6f93-4464-a53e-1050253ae220} Writer Name: System Writer Writer Instance ID: {e4a8b0d4-a47f-4f4d-ac2c-e36404781f7e}
The access denied error is no longer happening but the backup is still unable to complete. I have granted the backup account administrator rights.
Any clues on how to proceed?
