We want to use the Bitbucket Server DIY Backup scripts provided by Atlassian (available here) as the basis to the backup system of our Bitbucket server. Before we can start using the scripts provided by Atlassian, we have to validate if the license covering the code is compatible with our legal requirements. But I can't find any license information. So do anyone know how the source of the Bitbucket DIY backup scripts are licensed?
