CDP architecture
The CDP gateway is configured on a NetBackup media server. Once configuration is done, NetBackup starts the nbcctd daemon on the CDP gateway. This process services all I/Os from ESX and enables other NetBackup components on the gateway to take backup. To backup this data, you also need to configure an MSDP or OST accelerator-based STU. You can configure multiple CDP gateways and MSDP/OST accelerator-based STUs as required. NetBackup REST APIs for CDP are a web API interface to leverage this feature. Refer NetBackup REST APIs Swagger documentation for more information.
