Backup methods
There are several different methods to backup and restore a WAS node; one of them is to use the backupConfig and restoreConfig command-line tools that come with the product. Another one is to save the files inside the <WAS_HOME> directory tree using backup software like IBM Tivoli Storage Manager. Example A-1 shows the output when backing up a repository using the backupConfig command.
Example: A-1 Backing up a repository using backupConfig.bat
C:\WebSphere\DeploymentManager\bin>backupConfig.bat dm_2003-11-28.zip -nostop
ADMU0116I: Tool information is being logged in file

Independent of the backup strategy you implemented, it is recommended to take a backup before major configuration changes or updates, and having backups scheduled on a regular basis: on UNIX platforms, schedule backup jobs using the cron utility; on the Windows platform, use the Scheduler facility, or use your backup software's proprietary mechanisms to achieve the same.
Tip: The backupConfig (and also the restoreConfig) command takes the -nostop option which allows you to perform a backup in a production environment without stopping any service. |
In this appendix we solely focus on the steps necessary to restore a failed system in a Network Deployment configuration. Restoring a base configuration, that is, a standalone node, is straightforward and is not discussed here. Refer to chapter 10.7.5 in IBM WAS V5.0 System Management and Configuration: WebSphere Handbook Series, SG24-6195 for more information on backing up and restoring a standalone base node installation.
