Kindly note that when backing up the Data and Catalogs folder the job is failing with the following error.
Fimal error: 0xe00084af - The direcory or file was not found or could not be accessed.
Is the Advanced Open File option enabled in the backup job ? If yes, have you explicitly set it to choose the MS vss proivder ?
Secondly, do ensure the backup of the media server is preferably not conflicting with the schedules of other backup jobs.
P.S: This is an user-assisted forum and for really urgent issues, best to reach out to formal support lines such as technical support over the phone.
