I am seeing an issue where a Full VSS backup taken using Windows Backup in Server 2008 R2 completes successfully but Exchange transaction logs are not truncated. After the event ID 9622 "Exchange VSS Writer <instance xxxx> has processed the post-snapshot
event successfully" there is an Informational event logged which states "The Description for Event ID 0 from source wsbexchange cannot be found The following information was included with the event Service Started."
I'm not sure if the above event is relevant to the backup failing to clear event logs or is misleading and is simply pointing out that the Microsoft Exchange Server Extension for Windows Server Backup (wsbexchange) service has started. I receive no other
backup related events after this message and teh backups appear to complete successfully.
If I examine the system log I see events 7036 "The Microsoft Exchange Server Extension for Windows Server Backup service entered the running state." about the time the Exchange backup starts and again shortly after it completes The Microsoft Exchange Server
Extension for Windows Server Backup service entered the Stopped state.
I'm not sure where I can start troubleshooting this issue and until the backup product I use supports Exchange 2010 I have to manually clear the transaction logs after 30 days or so by enabling/disabling circular logging.
Any ideas appreciated
