Backup Schedules Failing

We have got backups set regularly each day. A full backup early in the
morning then a partial one every hour. These run time and the jobs for them
are in the SQL-SERVER Agent. After a few weeks the partial backups start to
fail. The full backups are fine. There is plenty of space an no errors in
the logs. When looking at the partial backups unser SQL-Server agent and
looking at the the schedule the box matked Enable is unchecked. We reset
the backup by clicking this box. It runs fine for a few wekes when it fials
again and the box has become unchecked? Has anyone got any ideas why this
might happen?
What version and service pack ? Might be related to
