I am having trouble with the cleanup task for the client backup database. On Sunday I got notice from the server the the cleanup task did not execute successfully in >14 days. The history for the task is enabled but does not show any entries. The "last run" date is 3/9/13. I executed the cleanup task manually from the task scheduler, which worked apparently problem free. Upon completion the successful execution appeared in the history. I checked the Event Viewer->Application and Services Log->Microsoft->Windows->Windows Server-> Admin log, which showed event IDs 274 and 275 for the manual executions, but none associated with the Saturday 11:59 PM scheduled execution. The task is enabled.
Can anyone help me debug why the task is not executing as scheduled?
