// Restores a backup to a server that is in a CONNECTION_LOST , HEALTHY , RUNNING ,
// UNHEALTHY , or TERMINATED state. When you run RestoreServer, the server's EC2
// instance is deleted, and a new EC2 instance is configured. RestoreServer
// maintains the existing server endpoint, so configuration management of the
// server's client devices (nodes) should continue to work. Restoring from a backup
// is performed by creating a new EC2 instance. If restoration is successful, and
// the server is in a HEALTHY state, AWS OpsWorks CM switches traffic over to the
// new instance. After restoration is finished, the old EC2 instance is maintained
// in a Running or Stopped state, but is eventually terminated. This operation is
// asynchronous. An InvalidStateException is thrown when the server is not in a
// valid state. A ResourceNotFoundException is thrown when the server does not
// exist. A ValidationException is raised when parameters of the request are not
// valid.
