Hi,
Is this the exact error message that you are getting after the backups "a0008486 - media operation terminated by the user".
If yes, please go to the job propoerties and deselect the option 'Enable automatic cancellation' under schedule.
Re run the job and check out the results.
If no, I would like to know the exact error message that you are getting along with the error code.
NOTE : If we do not receive your intimation within two business days, this post would be assumed answered and archived.
Thanks.
