Question : difference between Maintenance plan and scheduled jobs in SQL Server 2000

Hi, I would like to know what difference between Maintenance Plan and Scheduled Jobs. For example, in maintenance plan I set up a Weekly full backup (every Sunday) and a daily Transaction log backup every 3 hours. And in Scheduled jobs I set up a differential backup on the weekdays (Mon-Sat). But When I tried to restore the differential backup files on top of the full weekly backup, I got an error. My goal is to restore any point of failure (within 3 hours).

Please let me know what I have done wrong

Code is appreciated.

Thanks

A maintenance plan is a unit of work that you use to backup databases, reindexing, etc.  Typically, these are ran at routine intervals through the use of a Scheduled Job using the Sql Agent service.

What is your error?
