2.4.2. Configuration File History
The application server configuration files include
standalone.xml, as well as the
host.xml files. While these files may be modified by direct editing, the recommended method is to configure the application server model with the available management operations, including the Management CLI and the Management Console.
To assist in the maintenance and management of the server instance, the application server creates a timestamped version of the original configuration file at the time of startup. Any additional configuration changes made by management operations result in the original file being automatically backed up, and a working copy of the instance being preserved for reference and rollback. This archival functionality extends to saving, loading and deleting snapshots of the server configuration to allow for recall and rollback scenarios.
