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?

• B.Increase Maximum data streams per client
• C.Increase Maximum concurrent jobs for the storage unit
• D.Increase Maximum jobs per policy
