Recently when i tried TSM TDPSQL backup with the new server on SQL Server 2008 failed with the error below.
“ TSM TDP SQL Error: Could not load file or assembly 'Microsoft.SqlServer.Smo, Version=220.127.116.11, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified. Process Exit Code 1914. The step failed. “
After investigation, installed the TSM TDP SQL version 18.104.22.168 from 5.5.0. This resolved the issue.
