Abstract
An approach to providing failure protection in a loosely-coupled cluster environment. A node in the cluster generates checkpoints of application data in a consistent state for an application that is running on a first node in the cluster. The node sends the checkpoint to one or more of the other nodes in the cluster. The node may also generate log entries of changes in the application data that occur between checkpoints of the application data. The node may send the log entries to other nodes in the cluster. The node may similarly receive external checkpoints and external log entries from other nodes in the cluster. In response to a node failure, the node may start an application on the failed node and recover the application using the external checkpoints and external log entries for the application.
