A.2.6.3 Restoring a System Backup
Use the YaST System Restoration module to restore the system conguration from
a backup. Restore the entire backup or select specic components that were corrupted
and need to be reset to their old state.
1 Start YaST > System > System Restoration.
2 Enter the location of the backup le. This could be a local le, a network
mounted le, or a le on a removable device, such as a oppy or a DVD. Then
click Next.
The following dialog displays a summary of the archive properties, such as
the lename, date of creation, type of backup, and optional comments.
3 Review the archived content by clicking Archive Content. Clicking OK returns
you to the Archive Properties dialog.
4 Expert Options opens a dialog in which to ne-tune the restore process. Return
to the Archive Properties dialog by clicking OK.
5 Click Next to open the view of packages to restore. Press Accept to restore
all les in the archive or use the various Select All, Deselect All, and Select
Files buttons to ne-tune your selection. Only use the Restore RPM Database
option if the RPM database is corrupted or deleted and this le is included in
the backup.
6 After you click Accept, the backup is restored. Click Finish to leave the module
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 conguration les, or a
corrupted boot loader conguration 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 conguration 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 conguration.
Recover from a badly installed device driver or unusable kernel.
