Introduction

This section describes how to back up cluster and configuration data and replace a controller node.

The following are required to perform the procedures described in this guide.

1. A remote FTP server with at least 50GB of free disk space. You must create an FTP account (user name and password) before starting these procedures.
2. If you are restoring to a multi node cluster environment, all backup files must be taken around the same time. If the backup files are out-of-sync, the restore process may be unsuccessful.
