Hi,
I have some problems with the backup of MSSQL databases and I need your help.

TSM 5.1.1.6 Server on AIX 4.3
TSM 5.1.7 Client
TDP for MSSQL 5.1.5 

Backup fails most of the time for some databases (they are not the same every 
time) and sometimes completes without errors.

I'm receiving the folowing errors:

In the Windows event log:

20.1.2003 21:00:25 MSSQLSERVER Error (2) 17055 NT AUTHORITY\SYSTEM NAUTILUSA 
18210 :

DESCRIPTION=N'TDPSQL-00000AF0-0000 (TDP MS SQL V2)'

In the TDP schedule log:

and so on...

Any help is appreciated
