NetApp Cloud Volumes ONTAP (CVO)
NetBackup Snapshot Manager for Data Center supports NetApp CVO using NetApp storage array plug-in. You can use NetApp CVO as a replication destination for protecting on-premises arrays or as a filer. NetBackup Snapshot Manager for Data Center supports all the operations to protect NAS environments on NetApp CVO on AWS cloud.
If your primary server is on-premises and media server and backup hosts are in the cloud, for the firewall ports requirements, see:
https://www.veritas.com/support/en_US/article.100002391
To establish bi-directional connectivity between the backup hosts & CVO use inbound rules. See:
https://docs.netapp.com/us-en/bluexp-cloud-volumes-ontap/reference-security-groups.html
It is recommended to keep the backup host and the CVO in the same region, and preferably in the same VPC to reduce cloud networking costs during backup.
