In one embodiment the method includes the steps of determining by the primary node to initiate a checkpoint process; sending a notification to the secondary node, by the primary node, of an impending checkpoint process; blocking, by the primary node, I/O requests from the Operating System (OS) that arrive at the primary node after the determination to initiate the checkpoint process; completing, by the primary node, active I/O requests for data received from the OS prior to the determination to initiate the checkpoint process, by accessing the primary node data storage; and upon receiving, by the primary node, a notice of checkpoint readiness from the secondary node, initiating a checkpoint process to move state and data from the primary node to the secondary node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for checkpointing in a fault tolerant system","description":"A method and system of checkpointing in a computing system having a primary node and a secondary node is disclosed.
