the backup.

after the restore process is completed.
A.2.7 Recovering a Corrupted System
There are several reasons why a system could fail to come up and run properly. A
corrupted le system following a system crash, corrupted conguration les, or a
corrupted boot loader conguration are the most common ones.
A.2.7.1 Using the Rescue System
openSUSE contains a rescue system. The rescue system is a small Linux system that
can be loaded into a RAM disk and mounted as root le system, allowing you to access
your Linux partitions from the outside. Using the rescue system, you can recover or
modify any important aspect of your system:
• Manipulate any type of conguration le.
• Check the le system for defects and start automatic repair processes.
• Access the installed system in a “change root” environment.
• Check, modify, and reinstall the boot loader conguration.
• Recover from a badly installed device driver or unusable kernel.
