Which cloud setting under the Scalable Storage host property should be modified to reduce network...

The correct setting is Network Connections > Maximum concurrent jobs. In Cohesity NetBackup documentation, the Scalable Storage host property is accessed from Hosts > Host properties, selecting the media server, editing media server properties, and choosing Scalable storage. These settings cover cloud encryption, metering, bandwidth throttling, and network connections between NetBackup hosts and the cloud storage provider. The key requirement in the question is to reduce network use by limiting the number of parallel backup streams. Cohesity documents Maximum concurrent jobs as “the default maximum number of concurrent jobs that the media server can run for the cloud storage server,” and notes that when jobs exceed the allowed connection count, additional backup or restore jobs fail after the maximum is reached. By reducing this value, the administrator directly limits simultaneous cloud backup streams and therefore reduces concurrent network consumption. The other options control different behaviors: Metering interval affects reporting collection frequency, Total available bandwidth defines the cloud connection speed, and Sampling interval controls how often bandwidth usage is measured for throttling.
