I am having issue with incremental backup for one of the server. The daily backup failed with return code 12. The server is running on Windows 2012. When I check dsmsched.log there is error
'ANS1512E Scheduled event 'DAILY' failed. Return code = 12'.

When I check dsmerror.log, there are a lot of ANS9999E error.

05/12/2015 22:25:44 ANS9999E ..\..\common\winnt\ntrc.cpp(765): Received Win32 RC 1168 (0x00000490) from GetBackupStreamSize(): uc_CreateFile. Error desription: Element not found.

Has anyone encounter this issue before and please advise on how to solve the issue?

Hi,

Before you can solve this, you will need to do some further troubleshooting. Was the snapshot for a SystemState backup or file backup?

As you saw from the logs, the snapshot failed with ANS2698E, which means:
ANS2698E

Snapshot operation failed.
Explanation

If you are performing a VSS or LVSA snapshot based operation, it is possible that the snapshot was not large enough to contain all the changes made to the file system after the snapshot was created. This could cause the snapshot to become invalid thereby preventing the TSM client from reading the snapshot.
System action

The requested operation stopped.
User response

Examine the client error log for additional messages related to this error. Perform corrective actions indicated by the messages, then try the operation again.

The ANS9999E errors give a bit more context to this with "Received Win32 RC 1168". So the VSS snapshot failed because of Windows error code 1168, however, that error doesn't give much help:
ERROR_NOT_FOUND
1168 (0x490)
Element not found.

I suggest that you test if you can do a snapshot of that volume outside TSM. You will have to look up higher in the dsmsched.log to see which drive was being processed for that failed snapshot, a systemstate backup or the backup of a specific drive.

You can use these instructions to test VSS functionality by itself: http://www-01.ibm.com/support/docview.wss?uid=swg21699984

If the snapshot was for a SystemState backup, scroll down to the section titled: Test a snapshot of SystemState

If the snapshot was for a file backup, scroll down towards the bottom, look for the section titled: Test a snapshot of a disk for Open File Support or Online Image with snapshot provider to VSS

Perform the test(s) and if you get any errors while creating the snapshot for either test using diskshadow, that means there is a problem that there is a problem with either VSS or Windows that will need to be investigated further.
