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.

IMPORTANT: A restore operation is required to recover from catastrophic failures, not to fix minor problems that can be resolved in other ways. |

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. In this case, the backup file must have been created from an appliance running the same version of Insight Control server provisioning.

IMPORTANT: To successfully restore an appliance from a backup file, the appliance must be running the same version of the firmware as the backup file; their version numbers must match exactly. Also, before running the restore operation, be sure that the appliance that you run the restore operation on has exactly the same network settings as the original appliance. If the backup file used to restore the appliance is larger than the 4GB upload limitation of the Internet Explorer browser, consider using Firefox or Chrome instead. If a nonrecoverable error occurs during the restore operation, you need to download a new appliance template as described in the Insight Control server provisioning Installation Guide, available at www.hpe.com/info/insightcontrol/docs. |

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 the restore operation cannot resolve automatically. They are presented as alerts. After the restore operation, the appliance administrator must manually resolve any remaining inconsistencies.

You can use the UI to upload a backup file and restore the appliance from it. You can also use REST APIs for this purpose.
