2.8.1 Backup Copy of the System Areas
The YaST backup module enables you to create a backup of your system.
The backup created by the module does not comprise the entire system,
but only saves information about changed packages and copies of critical
storage areas and configuration files.
Define the kind of data to save in the backup. By default, the backup in-
cludes information about any packages changed since the last installation.
In addition, it may include data that does not belong to packages them-
selves, such as many of the configuration files in /etc or the directories
under /home. Apart from that, the backup can include important storage
areas on your hard disk that may be crucial when trying to restore a sys-
tem, such as the partition table or the master boot record (MBR).
2.8.2 Restoring the System
The restore module, shown in Figure 2.19 on the next page, enables restora-
tion of your system from a backup archive. Follow the instructions in YaST.
Press ‘Next’ to proceed to the individual dialogs. First, specify where the
archives are located (removable media, local hard disks, or network file
systems). A description and the contents of the individual archives are dis-
played, enabling you to decide what to restore from the archives.
Additionally, there are two dialogs for uninstalling packages that were
added since the last backup and for the reinstallation of packages that were
deleted since the last backup. These two steps enable you to restore the ex-
act system state at the time of the last backup.
