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.
