28 Restoring an appliance from a backup file
This chapter describes how to use the UI, REST APIs, or a custom-written PowerShell script to restore
a corrupted appliance from a backup file. A restore operation is required only to recover from
catastrophic failures, not to fix minor problems that can be resolved in other ways.

For more information about restoring an appliance, see the online help for the Settings screen.
IMPORTANT: Do not use any hypervisor-provided capabilities or snapshots to restore an HP
OneView appliance because doing so can cause synchronization errors and result in unpredictable
and unwanted behavior.
28.1 Roles
Users with Infrastructure administrator or Backup administrator privileges can create and download
backup files, however, only an Infrastructure administrator can restore an appliance from a backup
file.
28.2 Restore operation overview
You can restore an appliance from a backup file that was created on the same appliance or, if
an appliance fails and cannot be repaired, from a backup file from a different appliance.
During a restore operation, the appliance firmware reconciles the data in the backup file with the
current state of the managed environment. There are some discrepancies that a restore operation
cannot resolve automatically. After a restore operation is complete, the Infrastructure administrator
must manually resolve any remaining inconsistencies, which are identified by activities.
See also “Post-restoration tasks” (page 224) .
IMPORTANT: After the restore operation, you need to upload the firmware baselines required
by your server profiles, enclosures, and logical interconnects. Refer to each profile's Firmware
baseline
setting to determine the file name for the required baseline. You do not need to upload
the default baseline, HP Service Pack for ProLiant - Base Firmware, which is included
in the appliance image.
You should only use a restore operation to recover from catastrophic failures. Do not use it for
minor problems that can be resolved in other ways.
Restoring a backup file replaces all management data and most configuration settings on the
appliance.
The appliance is not operational during a restore operation.
It can take several hours to perform a restore operation.
A restore operation cannot be canceled or undone after it has started.
