30 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.

IMPORTANT: Do not use any hypervisor-provided capabilities or snapshots to restore an HP

30.2 About restoring the appliance
Restoring an appliance from a backup file replaces all management data and most configuration
settings with the data and settings in the backup file, including user names and passwords, audit
logs, and available networks.
The appliance is not operational during the restore operation and it can take several hours to
perform; the more resources and devices to restore, the longer the restore operation takes. A restore
operation cannot be canceled or undone after it has started. The appliance blocks login requests
while a restore operation is in progress.

an appliance fails and cannot be repaired, from a backup file from a different appliance. In this
