Abstract

An NFS export is created on a node of a data protection appliance. The export includes a backup to be accessed by an access object service hosted by the node. The node is in a cluster of nodes including other AOB services and NFSv3 servers accessible via external IP addresses. Each AOB service has access to other portions of the filesystem assigned to other AOB services. The export is mounted at an NFSv3 client which conducts data protection IO on the export using an external IP address to the node. A mapping of the export is maintained. Upon a node failure, resource utilization of other nodes is probed to select a failover node. The mapping is consulted to identify the IP address associated with the failed node. The IP address is migrated to the failover node.
