SQL Server 2000 maintenance plan

Can you tell me what type of locks and other information maintenance plans need when running against a SQL Server 2000 database? I am looking for the internals of how the maintenance plan works.
When creating a maintenance plan, SQL Server jobs are created that break down the maintenance tasks selected into multiple jobs. The jobs then use the sqlmaint utility to complete the task. The tasks that can be run using the sqlmaint utility include database and log backups, DBCC CHECKDB and index rebuilds. These tasks have been written in SQL Server, so they can be run during normal user activity on the database, but locks are applied that can conflict.

So when scheduling any of these tasks, it is a good idea to run these during low usage time. The only real difference...

would be running transaction log backups. These should be scheduled to run on a schedule that will help minimize data loss.
