Tivoli Storage Manager and SQL backup

The script that was used as a template for initiating the SQL backup from the TDP agent is simply a bat-file. It isn’t very complicated and quite basic. Since deploying this backup within a datacenter and dealing with a few different SQL-servers installed in quite a few different ways – it seemed that this script had as many variations as we had SQL-servers installed. The main flaws were around the fact that multiple SQL instances weren’t detected and that the transaction-log weren’t truncated when the backup had been run for databases that were set to recovery mode FULL. Inorder to make this more manageable the following improvements were made;

  • Detect all SQL instances via the local the registry – based on Jay’s blog
  • Exclude Windows Internal Databases
  • Run through all databases in each instance. Verify if there are any offline instances and databases
  • Backup all databases or each database that are online.
  • Run a backup of transaction log and truncate it – some things based on SpaghettiDBA
  • Track all errors and exit the command with the error if one occurs to allow TSM to report a failed backup

It does not;

  • Detect if a SQL instance is offline
  • Detect if SQL is not installed and then fail

Why a bat-file?
All servers we are supporting doesn’t have Powershell. A reality…

rem The two lines below put a date/time stamp in a log file for you.

rem Note: You can change "sqlsched.log" to whatever you prefer in

rem lines below.

rem ==================================================================

date < NUL >> %sql_dir%\sqlsched.log

time < NUL >> %sql_dir%\sqlsched.log

rem ==================================================================

rem Now call the command-line interface to do the backup:

rem

rem Replace "srvrname" with the name of the options file name you

rem plan to use.

rem

rem If SQL authentication is being used and the SQL login settings have

rem not been stored via the GUI, you must also specify the /sqluser and

rem /sqlpassword options on the command below.

rem

rem In this example, we use the '*' to back up all of the databases

rem on the SQL server. Note that database 'tempdb' will not

rem be backed up.

rem

rem Note: You can change "sqlsched.log" and "sqlfull.log" to

rem whatever you prefer.
