Under the host properties of the media server there is a section called 'Scalable Storage' within which there is the ability to configure Cloud bandwidth throttling options for read and write operations and also for different time windows of the day.
My question is if this option applies to NetBackup Cloud Catalyst only or if it is the correct location to manage the ISP bandwidth for MSDP-Cloud environments for NetBackup 9.1?
Scalable Storage tab appears in the Media Server properties window if the host is supported for cloud storage. Details about Scalable Storage - https://www.veritas.com/content/support/en_US/doc/58500769-150013608-0/v59314583-150013608
From the Cloud Administrator guide, the settings are supported for the media server which is a cloud storage server for supported cloud storage providers.
