Re: Cannot backup Exchange VSS Error

You're failing during the consistency check of the logs. Descibe your disk
layout. How much space do you have allocated for shadow copies?

If your database is on the system volume, and you run both a system state
and exchange backup at the same time, you get a conflict like this. If you
don't have enough space for the shadoiw copy you can get a conflict like
this. If you run multiple SG backups one after the other and don't have
enough space for shadow copies ....

I'd investigate that path.

Thanks for the suggesion John. I tried to create a Database-Level
backup only. Still the backup failed. In application log First the
same VSS error showed up then some information entries telling me that
storage gourp is froze, thawed ready for copy etc. One infromation
entry mentions dirty shutdown state:

Log Name: Application
Source: Storage Group Consistency Check
Date: 9/25/2008 11:13:11 AM
Event ID: 200
Task Category: Database Header Validation
Level: Information
Keywords: Classic
User: N/A
Computer: email.company.net
Description:
Instance 1: Database headers have been successfully validated. All
databases are in a dirty shutdown state. To bring these databases to a
clean shutdown state, log generations 8367 (0x000020af) to 8379
(0x000020bb) will be required.

The log generation numbers are different each time I try to back up
and as you can see it is an information entry not an error.

this is followed by several more info. entries about different tasks
Log file integrity check etc and all show completed tasks.

Then these four errors appear:

1. Log Name: Application
Source: Storage Group Consistency Check
Date: 9/25/2008 11:27:03 AM
Event ID: 402

2. Exact same error as mentioned in my original post about IVssWriter
callback interface.
