    RESTORE Configuration Database

    Restores from a previously created Backup Configuration Database archive file.

    Warning: Note that the backup and restore functions are meant as entire system replacements. The restore function requires that the IP address and hostname of the ScaleArc device be identical to the one captured in the backup archive file. These functions are meant to create a replacement ScaleArc system, should the hardware suffer a catastrophic failure. They are not meant to migrate a configuration from one ScaleArc system to another.
