in the /var/log/parallels.log on the source node* there are messages:

10-27 04:00:10.503 F /disp:9665:922466/ Can't connect to the target dispatcher: host '192.168.255.1' port 64000

RATIVELY (0x80000510) )

*: source hereafter denotes the hardware node that hosts the VE from which the backup is made.

Cause

Source node cannot connect to the target hardware node (192.168.255.1 in example above) of the backup.

Resolution

  1. Check connection from source node to port 64000 on target node (the port where dispatcher is listening)
  2. Access the target node, verify that parallels-server service is running,
  3. Verify that there are no problems in network communication between souce and targer nodes.
