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....
