A NetBackup appliance is not backing up data as expected. What steps can be taken to troubleshoot the problem?

An administrator has configured a Storage Lifecycle Policy (SLP) to protect a large number of clients which directs backups to Advanced Disk, then duplicates the images to tape. The administrator is experiencing an SLP backlog, which is causing backups to fail. The current values of key configuration settings are listed below:
Host Properties - Maximum data streams per client = 1
Policy Settings - Maximum jobs per policy = 20
Disk Pool Settings - Maximum I/O streams = 20
Storage Unit Settings - Maximum concurrent jobs = 20
Storage Unit Settings - Multiplexing level = 20
Which parameter should the administrator change to reduce the SLP backlog and allow the backups to complete successfully?
