This document provides information on connecting Confluence to an external database.
Choosing an external database
Note: Take time to choose your database wisely. The XML backup built into Confluence is not suited for migration or backup of large data sets. If you need to migrate later, you'll need to use a third party database migration tool.

About the embedded H2 database
Your Confluence installation includes an embedded H2 database, to enable you to try Confluence without setting up an external database. The embedded H2 database is only supported while you are evaluating Confluence. You must migrate to a supported external database before using Confluence as a production system.
To find out if you are still using the embedded database, go to > General Configuration > Atlassian Support Tools > Health Check.
Here are the setup instructions for the supported databases:
- Database Setup for Oracle
- Database Setup For MySQL
- Database Setup for PostgreSQL
- Database Setup for SQL Server
For solving database-related problems:
- Troubleshooting External Database Connections
- How to Interpret DB2 Error Codes
