Checking network connections

Acronis Backup & Recovery for vCloud components use TCP ports to communicate with VMware vCloud components and with each other. Make sure that your firewalls and other components of your network security system allow connections through these ports.

The diagram below illustrates the network connections that are necessary for the backup service to function.

The arrow direction shows which component initiates a connection. The text shows the destination port. The source port is taken from a standard range, depending on the operating system:

• Agent for vCloud and Agent for ESX(i) use the range 32768–61000.
• The management server and the external SQL Server use the range 1025–5000 (if installed in Windows prior to Windows Vista) or 49152–65535 (if installed in Windows Vista and later).

Normally, the standard ranges are already open.

For the machine with Agent for vCloud, eth0 and eth1 show the network adapter through which the connection is performed.

* The port is configurable. The diagram shows the default value.
