Backup job not getting completed

[zak2011]

Hi,

I have a BE12.5 server in a branch office. When the weekly job runs, it doesnt get completed and the tape ejects automatically. So when i see the status of the job, it says the following:-

Completed status: Canceled, timed out
The job was automatically canceled because it 
exceeded the job's maximum configured 
run time.

How do i configure the job so that it completes the write operation to tape.

Thanks,

I tried the job again and the same thing happens. Its very strange that the tape is ejecting out and the job history says cancelled.

The job log says this:
