If you need to do a complete Disaster Recovery backup, you should make sure you have the following components or RPMs:
- QueueMetrics
- Java SDK
- Tomcat (or a servlet container)
- MySQL connector
- Your licence key
- Your web.xml
- Your configuration.properties
When taking a snapshot, consider that the QM webapp is read-only, so if you have the setup plus for conveniency the current web.xml and configuration.properties, that us enough. All live data stays in the database, so the QM database has to be backed-up.
