Multi-Account support in single provider plugin
Starting with NetBackup 11.1, assets across multiple cross-accounts can be protected using a single provider configuration created from the source account. This eliminates the need for multiple agent services - one for each AWS account in the NetBackup Snapshot Manager deployment - reducing unnecessary resource consumption and simplifying management. To use this feature, both the NetBackup Snapshot Manager and the NetBackup Primary Server must be upgraded to version 11.1.
Note:
You cannot modify the configuration of an existing cross-account setup that is already protected using a different cross-account configuration.
