Confluence Server is where you create, organise and discuss work with your team. Capture the knowledge that's too often lost in email inboxes and shared network drives in Confluence – where it's easy to find, use, and update. Give every team, project, or department its own space to create the things they need, whether it's meeting notes, product requirements, file lists, or project plans, you can get more done in Confluence.

(amongst other things) we recommend mounting a host directory as a [data volume](https://docs.docker.com/userguide/dockervolumes/#mount-a-host-directory-as-a-data-volume):
For evaluating Confluence you can use the built-in database that will store its files in the Confluence Server home directory. In that case it is sufficient to create a backup archive of the directory on the host that is used as a volume (`/data/your-confluence-home` in the example above).
Confluence's [automatic backup](https://confluence.atlassian.com/display/DOC/Configuring+Backups) is currently supported in the Docker setup. You can also use the [Production Backup Strategy](https://confluence.atlassian.com/display/DOC/Production+Backup+Strategy) approach if you're using an external database.
In Mac OS X with Docker version 1.11.0, when running with docker-machine, there is a bug where the directory specified for `CONFLUENCE_HOME` in a volume mount will not have the correct permission, and thus startup fails with a permission denied error:
Error writing state to confluence.cfg.xml
com.atlassian.config.ConfigurationException: Couldn't save confluence.cfg.xml to /var/atlassian/confluence-home directory.
See https://github.com/docker/docker/issues/4023 for details.
To work around this issue, use a different host operating system other than Mac OSX until a newer release of Docker fixes this issue.
