摘要
The present invention describes a method and system for providing cluster replicated checkpoint services. In particular, the method provides cluster replicated checkpoint services for replicas of a checkpoint in a cluster. The cluster includes a first node and a second node, which are connected to one another via a network. The replicas include a primary replica and a secondary replica. The method includes managing the checkpoint that contains checkpoint information, and creating the primary replica in a memory of the first node. The primary replica contains first checkpoint information. The method also includes updating the primary replica so that the first checkpoint information corresponds to the checkpoint information, creating the secondary replica that contains second checkpoint information in a memory of the second node, and updating the secondary replica so that the second checkpoint information corresponds to the checkpoint information.
