Backup and Restore Nexus OSS 3

I was wondering if there is a standard way to backup and restore a Nexus OSS 3 Artifact Repository.

Is it enough to backup the "data" directory and copy it to a running new instance?

I use different types of repositories - Maven, NPM, Docker etc.

In Nexus Repository Manager 3.2 there will be a supported Backup/Restore feature. Your approach seems fine, a few notes:

• back up your data directory while Repository Manager is stopped (prevents db files being in an inconsistent state)
• test your restoration procedure to ensure it works
