Prerequisites

To perform operations described in this section, Acronis Backup Management Server uses a number of TCP ports:

• Ports 443 and 902 are used to access the vCenter Server and ESX(i) hosts.
• Port 9876 is used to access Agent for VMware (Virtual Appliance).

If the management server uses a custom firewall, ensure that this firewall allows outgoing connections to these ports. Windows Firewall is configured automatically by Acronis Backup.

If the traffic from the management server to the vCenter Server, the ESX(i) hosts, or the agents goes through a router or a similar network device, ensure that the device does not block this traffic.

No special configuration is required on the vCenter Server or the ESX(i) hosts.
