Hi,
Backup job has been failed due to "0xe0001904 - A failure occurred querying the Writer status" error.
A review of the event logs on the Exchange server at the time of the failure reports:
Event ID : 9840
Event ID: 9814
Event ID: 9609
As per article - http://support.microsoft.com/kb/930800
I have restarted the Exchange server. But still i have received the above event id' even after server reboot.
All the VSS writers are in stable state now.
Server OS = windows 2008
Exchange server = Exchange 2007
Job log Error as below:
Backup- FTL4V-79-57344-6404 - AOFO: Initialization failure on: "\\XYZ\Microsoft Information Store\First Storage Group". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS).
Snapshot provider error (0xE0001904): A failure occurred querying the Writer status. Writer Name: Exchange Server, Writer ID: {76FE1AC4-15F7-4BCD-987E-8E1ACB462FB7}, Last error: The VSS Writer failed, but the operation can be retried (0x800423f3), State: Failed during prepare snapshot operation (8).
There is sufficient Free space available on all System drives.
Please let me know why backup job is still failing....

If AOFO is explicitly enabled in the backup job properties, disable it. Ensure the backup is not conflicting with the exchange maintenance schedule either.
Lastly, try this KB as well ~ http://support.microsoft.com/kb/930800

Issue this command in a command prompt.
vssadmin list writer
If there are any writers that have errors, you need to restart the server to clear the errors.
