Looks to be a DB structural integrity issue. You probably need to audit/fix the bad table(s) or record(s).

This person had the same issues> http://adsm.org/forum/showthread.php...P-MSSQL-backup

Dear all

As we can backup all remain database to TSM Server , the issue can only come from MSSQL
database setting include : Access Right , Structural , Configuration, Database Logical Files setting.

After doing a health check on your Microsoft SQL Server , i can clarified the issue root cause come
from Page Verify Configuration

Issue root cause:
================================================== ===========================
Database page verify method on Microsoft SQL Server Database GVSIS
and GVSIS_DEV is Torn page detection. Torn page detection does not
completely fix a DB structural integrity issue.
================================================== ===========================

Setting changed:
================================================== ===========================
Page verify configuration changed from Torn page detection to Checksum
================================================== ===========================


Thanks and Best Regards.

Hello hungng89,

I think solutions are

TDP - Put QUERYOPTIMIZATION 0 in tdpsql.cfg (Configuration file by default) or SQL - sp_dboption 'MyTroubleDatabase', 'autoclose', 'FALSE'
for each affected database.
