Backing up and Restoring Data
4.2 Backing up and restoring PCU partitions locally
Figure 4-4
Restoring partition E (Windows)
A local backup image can also be used to restore only partition E: (Windows) (Windows) if
required. This can be necessary if, for example, Windows can no longer be booted after a
system crash or uncontrolled shutdown of the PCU (partition E data restore).
Figure 4-5
Theoretically, any of the local backup images currently located on partition D: can be used in
a partition data restore or a partition E data restore.
Of course, in the case of partition E data restore, the local backup image used must be
chosen with great care: The registry entries of all applications installed on partition F: are
also expected on the partition E: to be restored.
It is, therefore, practical to always have a particular local backup image (emergency backup
image) defined, which can be loaded in case of an emergency (Windows cannot be booted)
using partition E data restore without impairing execution of the installed applications.
Definition of a local backup image for a possible emergency and simple starting of the
partition E data restore in the event of an emergency are supported in the Service menu.
The maximum number of local backup images (≤ 7) stored at the same time on partition D:
can be set.
