 being able to `restore` from a backup requires stopping the nexus service. And this is not possible with the official image, as described in this bug report: https://issues.sonatype.org/browse/NEXUS-23442

 The travel audience Nexus Docker image provides the following features that are not present in the official image:
+
 * uses `runit` to run nexus under a secondary process
 * uses an Alpine base image, instead of RedHat's UBI8
 * provides an optional flag to make sure all mounted data is owned by the `nexus` user _(nexus will have issues if that's not the case)_
