Info

236 Start-Up use traceroute fully_qualified_domain_name (executed as root) to track the network route these requests are taking. This command lists any gateway (hop) a request from your machine passes on its way to its destination. It lists the response time of each hop and whether this hop is reachable at all. Use a combination of traceroute and ping to track down the culprit and let the administrators know. Once you have identified the cause of your network trouble, you can resolve it yourself (if the problem is located on your machine) or let the system administrators of your network know about your findings so they can reconfigure the services or repair the necessary systems. 9.6 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 the status quo from before your system failed. SUSE Linux 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. 9.6.1 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: a Select Profile Management → Add. b Enter a name for the archive. c Enter the path to the location of the backup if you want to keep a local backup. For your backup to be archived on a network server (via NFS),
enter the IP address or name of the server and the directory that should hold your archive. d Determine the archive type and click Next. e Determine the backup options to use, such as whether files not belonging to any package should be backed up and whether a list of files should be displayed prior to creating the archive. Also determine whether changed files should be identified using the time-consuming MD5 mechanism. Use Expert to enter a dialog for the backup of entire hard disk areas. Currently, this option only applies to the Ext2 file system. f Finally, set the search constraints to exclude certain system areas from the backup area that do not need to be backed up, such as lock files or cache files. Add, edit, or delete items until your needs are met and leave with OK. 3 Once you have finished the profile settings, you can start the backup right away with Create Backup or configure automatic backup. It is also possible to create other profiles tailored for various other purposes. To configure automatic backup for a given profile, proceed as follows: 1 Select Automatic Backup from the Profile Management menu. 2 Select Start Backup Automatically. 3 Determine the backup frequency. Choose daily, weekly, or monthly. 4 Determine the backup start time. These settings depend on the backup frequency selected. 5 Decide whether to keep old backups and how many should be kept. To receive an automatically generated status message of the backup process, check Send Summary Mail to User root. 6 Click OK for your settings to be applied and the first backup started at the time specified.
