hi,
Considering BE version 11d.
To save the jobs,
If the database is under the same instance of SQL on the SQL server. you need to use beutility.
Select the option "New Backup Exec Database Location".
Select the appropriate server and click OK to move the database.
For this, SQL database should be restored first on the crashed SQL server.
Remeber, you need to install the SQL instance on the server you are moving your database to.
To install, go to BE installer (\WINNT\INSTALL\SQL Express\).
To save catalogs,
Make sure you have the copy of \Program Files\Symantec\Backup Exec\Catalogs folder.
