He guys,
at the moment the exchange backup fails with the message Error on querying the writer status.
When I use the command "vssadmin list writers" I see that the Microsoft Exchange Writer shows that the "Microsoft Exchange Writer" has the status: Retryable Errors.
I found this TN: http://www.symantec.com/business/support/index?page=content&id=TECH60788
I dismounted the Exchange DBs and mounted them again afterwards.
Then I restarted the Information Storage service.
I used the BETEST.exe for a testbackup and the it ended without an error.
After that I run a manuell testbackup with backupexec and this worked as well without an error.
Today when I came in to the company the scheduled task for the weekend failed with the same error message and the writer status is again on "Retryable Errors".
We are using following environment:
Backup Server: Windows Server 2008 R2 - Backup Exec 2012
Exchange Server: Windows Server 2008 R2 - Exchange 2007
Any suggestions what I can do to get the backup working again?
