I think you are backing up to NAS and it is offline. You got to make sure that it is online before you start your job. You can check is status by going to the Storage tab

Make sure the disks are accessible from the media server when you login as the BESA.

Thanks for reply. The disks are accessible from the media server when i login as the BESA. Now i have a ideal. Maybe my NAS has problem. My NAS is QNAP and it has a new firmware. After upgrade firmware and monitoring. Thanks alot. Although my enlish is very bad and i couldn't describe my thanks. Thanks you very much

Restart all the BE services and see whether the disks come online.

Also, you can test the disks with this utility to see whether there are any incompatibilities.
