Continuing the discussion from OpenEnergyMonitor Development Plan Outline:
There have been a couple of instances lately where users have fallen foul while trying to update.
One of the issues I believe is there is no robust mechanism to backup Emoncms. By this I mean both system, data and settings. This should also work for all users not just EmonSD and EmonPi.
Whilst there is a backup module available (not part of core install), my experience is that this is not robust.
I believe this should be a core part of the offering when using EmonCMS and would like to see it in the roadmap.
