26.1 Roles
Users with Infrastructure administrator and Backup administrator privileges can create and download
backup files, however, only the Infrastructure administrator can restore an appliance from a backup
file.
The Backup administrator has the authority to use scripts to log in to the appliance and run scripts
to back up the appliance. This role is specifically intended for scripted backup creation and
download. HP recommends that users with this role should not initiate interactive login sessions
through the HP OneView user interface.
26.2 About backing up the appliance
HP OneView provides the ability to save your configuration settings and management data to a
backup file and enables you to use that backup to restore a corrupted appliance in the event of a
catastrophic failure.
The backup process involves creating a backup file and then downloading that file so that you can
store it to a safe and secure (off-appliance) location for future use.
For advice on creating and archiving a backup file, see “Best practices for backing up an
appliance” (page 184) .
For the procedure on creating a backup file from the UI, see “Back up an appliance” (page 185) .
IMPORTANT: In the unlikely event you need to restore the appliance , HP recommends backing
up your appliance configuration on a regular basis, preferably daily and, and especially:
•
After adding hardware
•
After changing the appliance configuration
•
Before and after updating the appliance firmware
The appliance stores one backup file at a time. Creating each subsequent backup file replaces the
current backup file. To prevent a backup file from being overwritten by a new backup file, download
and save the backup file to an off-appliance location before running the next backup process.
HP OneView provides a Backup administrator user role specifically for backing up the appliance
by permitting access to other resource views without permitting actions on those resources, or other
