Ports and communication protocols for Druva Phoenix

Druva Phoenix communicates with your hosts to backup and restore data on your hosts. Druva Phoenix talks to your Hyper-V host through ports and protocols that are secure for communication and transition of data.

Druva Phoenix uses Transport Layer Security (TLS) protocol for establishing the connection and initiating communication between Druva Phoenix components and your Hyper-V hosts.

The following diagram depicts the ports and communication protocols that are used by Druva Phoenix for secure connection and communication during the backup and restore operations.
