+## Local state recovery
+
+### Definitions
+
+**Local state** is a state of components, started tables, schemas, persistent and in-memory storages, partitions, RAFT groups, etc. on a given node. It also includes a projection of distributed cluster configuration.
+
+**Local state recovery** is changing local state in a way that every component on the node has its state configured and updated accordingly to cluster-wide configuration, topology, stored data, etc.
+
+**Vault** is a local storage of node configuration and a projection of cluster configuration. Vault has no log of historical changes. See [Vault](../../../../../../../../../vault/README.md).
+
+**Metastorage** is a distributed storage of cluster-wide meta information, including cluster [configuration](../../../../../../../../../configuration/README.md). Metastorage is located on a group of nodes, forming a RAFT group. It stores a history of changes.
