Abstract
High-availability cluster data protection is described. A computer executes a framework and a task dispatcher. The framework disables caching of internet protocol addresses queried from a network interface configuration of the computer. The task dispatcher receives a request to execute a data protection task, and determines whether the request is for a current cluster node. If the request is not for a current cluster node, the task dispatcher determines whether the request is for a logical host. If the request is for the logical host, the task dispatcher queries the network interface configuration to determine whether the internet protocol address of the logical host is locally available. If the internet protocol address of the logical host is locally available, the task dispatcher directs the request locally. If the internet protocol address of the logical host is not locally available, the task dispatcher directs the request to a remote node.
