Abstract
The present disclosure includes a method for transferring checkpoint information of a primary virtual machine from a primary host to a secondary host that includes, by the primary host, capturing checkpoint information from the primary virtual machine to a primary holding buffer on the primary host, generating a first number of partition state records from the checkpoint information, transmitting the first number of partition state records to the secondary host, receiving acknowledgements from the secondary host for a second number of partition state records, and tracking the second number of partition state records acknowledged by the secondary host.
