SQL Express 2005 Back up

Hi,

I have a customer using SQL Express 2005. My colleague had set up a batch file in Task manager to run a back up and data integrity daily. It was working fine up until Sept 1st.

The passwords have not changed, not in SQL and not on the server.

I am able to run the back up manually from the task manager.

The only item I can find in the log is the following: Any ideas where I can begin troubleshooting ?

Server resumed execution after being idle 15213 seconds. Reason: timer event.

Thanks,

Debbie
