An administrator has added a new client to a policy.

The correct answer is C because the failure is an authorization problem on the NetBackup client, not a basic network-connectivity failure. The job output explicitly states that nbumaster8 “is not an authorized server for host nbclient1,” followed by status 59: access to the client was not allowed. Cohesity NetBackup documentation maps status code 59 to “Access to the client was not allowed.” The controlling configuration is the client’s SERVER list. Cohesity states that the SERVER entry defines the list of NetBackup primary and media servers that can access the NetBackup client, and that media servers or other primary servers must be added for that client. Cohesity also explains that on UNIX servers and clients, the SERVER entries in bp.conf define the NetBackup servers that are allowed access, with additional entries identifying servers that can initiate scheduled backups. Therefore, the client rejected the backup request because the requesting server name was missing from the client’s server list or did not match the expected resolved name.
