3.3.2 Restore and auto-restore
Before a restore can be carried out, the USB stick must be prepared.
What is a restore / auto-restore?
Restoring a (previously created) backup is referred to as Restore.
Restore and auto-restore are identical as regards the data contents - they merely differ with regard
to the use (one-time restore or multiple restore)..
Functional principle of restore and auto-restore
A restore writes the (previously saved) backup data from the USB stick back to the internal flash
memory and the SD card.
• In the case of a restore first a backup is created by the controller, in order to be able to retrieve
the original state (in the event of an error).
• In the case of an auto-restore a restore without
a backup is carried out.
Differences between a restore/auto-restore
Restore Auto-Restore
•One-time
restore of a backup which was previously
configured.
• Select this process to restore the data bases of a
backup on an individual controller.
• When carrying out a restore a backup is created
beforehand.
•Multiple restore (restoring a backup) on an optional
number of controllers.
• If the USB stick is connected to another controller, the
auto-restore is carried out automatically (series
commissioning).
• When executing an auto-restore, a restore is carried
out directly - no
backup of the system is created
before.
