Issue description

The data-synchronisation script does not seem to sync data reliably.

Steps to reproduce the issue

Look at the number of projects in Django Admin, after sync script has run during the night

What's the expected result?

It should be the same number

What's the actual result?

There are currently 286 projects in fixmyplatform and 276 in fixmyplatform-develop
Also, individual project data is not congruent (e.g. project 340)

Also, I noticed that the script does copy the database without setting the target system to maintenance mode. The app is still running during the backup process and executing database queries during the backup.

I found this in the documentation for Heroku Scheduler:

If you are using Heroku Scheduler and Container Registry as your deployment method, your task must be accessible from the web image. There is no way to specify a non-web image for task execution.

The Readme suggests that no web image is used.

This is getting obsolete when migrating to Lightsail from Heorku.
