Abstract
The method of taking checkpoints of a virtual computing instance running in a first host computer at varying time intervals includes queuing outgoing network data packets of the virtual computing instance during execution of the virtual computing instance, triggering a process to take the checkpoint, the process including generating a checkpoint information packet and transmitting the checkpoint information packet to a second host computer, and upon receiving acknowledgement from the second host computer of receipt of the checkpoint information packet, releasing the outgoing network data packets of the virtual computing instance that have been queued and not released. The triggering time for the process to take the checkpoint is dependent on characteristics of workload executed by the virtual computing instance.
