Planning for high availability
To use HPE OneView in an HA (high availability) configuration, see your hypervisor documentation for specific requirements.
To maintain appliance availability, HPE OneView provides a backup feature to save your configuration settings and management data to a backup file. Hewlett Packard Enterprise recommends backing up your appliance, preferably daily and after any key configuration changes.
For more information see the "Backing up the appliance" and "Best practices for backing up an appliance" sections in the HPE OneView Help.
