1. A method for backing up virtual machines in a computing environment where the virtual machines are instantiated on one or more nodes in a cluster that includes proxy nodes, the method comprising:

  • identifying, by a processor, virtual machines to be backed up by proxy nodes that are configured to backup the virtual machines;

    identifying, by the processor, cluster shared volumes associated with the virtual machines to be backed up;

    taking, by the processor, a snapshot of the identified cluster shared volumes;

    determining, by the processor, a backup load associated with backing up the virtual machines;

    balancing, by the processor, the backup load across the proxy nodes by assigning the identified cluster shared volumes to at least some of the proxy nodes such that a total amount of data is balanced among the proxy nodes without requiring each of the proxy nodes to backup a same amount of data; and

    performing, by the processor, a backup operation through the proxy nodes.
