Windows Volume shadow copy error: 2155348129

Question

Developing a VSS writer app: see this error during backup, initiated by windows backup tool, is there defined error codes for 2155348129 from Microsoft?

"The backup operation that started at '‎2010‎-‎07‎-‎20T02:54:19.354000000Z' has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '2155348129'"

this does not happen when VSSwriter service (my application) is stopped.

any help is appreciated. Nothing useful found on technet.

hack: interestingly the back up works is when "windows partition is made active". Of course this leaves the system non-boot-able upon restart

Decimal 2155348129 is 0x807800A1 in hex. Quickly searching the Internet for this value takes me to http://blogs.technet.com/b/filecab/archive/2009/09/16/diagnosing-failures-in-windows-server-backup-part-1-vss-spp-errors.aspx, and the message "A Volume Shadow Copy Service operation failed. Please check "VSS" and "SPP" application event logs for more information."
