Location of Maintenance Plan's Back Up Database Tasks information (SQL Server 2005) I would like to know where in the database or on the file system the information about Back Up Database Task in the Maintenance Plans Tasks.

I can find the Job in msdb.dbo.sysjobs
I can find the Subplan in msdb.dbo.sysmaintplan_subplans

But I need to find where and how the Task is being stored.

Any help will be greatly appreciated.
In SQL 2000 they were in the msdb database.

Specific table information can be found here:
http://www.toadworld.com/platforms/sql-server/w/wiki/9438.msdb-databases.aspx#Database_Maintenance_Plan_Tables

In SQL 2005 maintenance plans are modified SSIS (or DTS) packages and are stored in the dbo.sysdtspackages90 table.  (from: http://www.sqlservercentral.com/Forums/Topic501078-5-1.aspx )

In SQL 2008 and 2012 they are in the sysssispackages table.
