several back-up features
Back-up & restore features are generally missing now.
Things that are essential to a production environment are IMO:
- back-up / restore all administration settings (i.e. all non-standard at least), esp. crucial when making small upgrades
- back-up / restore course(s): as this is linked with the repository, it could perhaps be best to handle this as an extension of repository export / import
- back-up / restore other applications: same as with courses
These last 2 is simply a way to back-up/restore all publications in all applications.
