CLUSTER CONFIGURATION BACKUP AND RECOVERY
First Claim
1. A method for restoring a node of a cluster network environment, comprising:
- identifying an integrity loss associated with a node within a cluster network environment; and
reviving the node as a restored node, the reviving comprising;
restoring a local configuration to the node;
restoring a cluster configuration to the node, the cluster configuration corresponding to cluster-aware information; and
introducing the restored node, corresponding to the node having the restored local configuration and the restored cluster configuration, to the cluster network environment based upon the cluster configuration of the restored node.

Abstract
A cluster network environment may comprise a plurality of nodes configured to perform various tasks, such as data I/O, storage, backup, etc. It may be advantageous to improve disaster recovery and reliability by creating backups that may be used to restore the cluster network environment and/or nodes therein. Accordingly, one or more techniques and/or systems are disclosed for restoring a cluster network environment and/or nodes therein. In particular, cluster configuration data, which may be stored in a healthy node or at a remote source, may be used to restore a node affected by an integrity loss. If the integrity loss affects the cluster network environment (e.g., a majority of healthy nodes are lost), then a new cluster network environment may be created from a healthy node or a restored healthy node. The creation of the new cluster network environment may be based at least in part on cluster configuration data.
