Well, we would also love to have something more easy to use.
We just started to run a node for this purpose (was ~5 days to fully catch up) but did not have time to look into it yet.
We need it for one of our projects. In case the project gets support by SDF we will open up our solution and probably can help you to provide you a DB dump on a specific time.
At the same tie this won't happen in the next few weeks.
In case you find a better solution, let us know.
Best,
Balazs
