US Patent 11182188 Elastic replication of virtual machines

Techniques for replicating virtual machine data is provided. A plurality of compute nodes running on a primary cluster determine the amount of virtual machine data cached within each compute node. Based on the amount of virtual machine data for a particular virtual machine, a particular compute node is assigned to replicate the data to a secondary cluster. The amount of particular virtual machine data copied to the secondary cluster is based on updated virtual machine data that belongs to a particular state of the virtual machine. The destination of the particular virtual machine data is based on available cache space and prior replication statistics for target compute nodes on the secondary cluster.
