51.5.1 NetworkManager Problems
If you have a problem with network connectivity, narrow it down as described in
(page 927). If NetworkManager seems to be the culprit, proceed as follows to get logs
providing hints on why NetworkManager fails:
1 Open a shell and log in as root.
2 Restart NetworkManager:
rcnetwork restart -o nm
3 Open a Web page, for example,
user to see if you can connect.
4 Collect any information about the state of NetworkManager in /var/log/
NetworkManager.
For more information about NetworkManager, refer to

51.6 Data Problems
Data problems are when the machine might or might not boot properly but, in either
case, it is clear that there is data corruption on the system and that the system needs to
be recovered. These situations call for a backup of your critical data, enabling you to
recover a system state from before your system failed. SUSE Linux Enterprise offers
dedicated YaST modules for system backup and restoration as well as a rescue system
that can be used to recover a corrupted system from the outside.
51.6.1 Backing Up Critical Data
System backups can be easily managed using the YaST System Backup module:
1 As root, start YaST and select System > System Backup.
2 Create a backup profile holding all details needed for the backup, filename of
the archive file, scope, and type of the backup:
