OneSpan Authentication Server Appliance can be easily replaced in the event of hardware failure, by restoring a backup from an old appliance to a new one.
If the replacement appliance is running an older product version than the version running on the appliance to be replaced, the replacement appliance must be upgraded before a backup can be restored.
The replacement appliance should run the same product version as the appliance being replaced. Upgrade paths for all features may not be supported when restoring a backup to a more recent version. If you are unsure, contact the supplier of your OneSpan Authentication Server Appliance.
The RAID option provides (hot swappable) hard disk redundancy, supporting full services even when a hard disk fails (see RAID).
