Usage: consul snapshot <subcommand> [options] [args]

  This command has subcommands for saving and restoring the state of the Consul
  servers for disaster recovery. These are atomic, point-in-time snapshots which
  include key/value entries, service catalog, prepared queries, sessions, and
  ACLs.

  If ACLs are enabled, a management token must be supplied in order to perform
  snapshot operations.

  Create a snapshot:

      $ consul snapshot save backup.snap

  Restore a snapshot:

      $ consul snapshot restore backup.snap


  For more examples, ask for subcommand help or view the documentation.
