Initial data collection exercise on automatic backups

Return to issue of whether to patch release psynet with backups disabled....

Try to reproduce the error (missing/out-of-date experiment entries in 'Deployments tab') in the following ways:

1. Local machine, demos/features/artifact_storage, run psynet debug local. Do we see the experiment in the deployments tab? If we wait 20 minutes, is the experiment still being updated with recent exports and correct numbers of participants?
2. psynet debug ssh the same demo with and without the following line commented out:

    artifact_storage = S3ArtifactStorage(root="artifacts", bucket_name="psynet-tests")

Does it work with one storage type but not the other?

What happens when you wait 6 hours, does it still work?

Do we see the weird repeated log messages?

Why is the artifact storage using the /tmp directory? Is this getting periodically wiped?

Can you inspect the directory where the artifact storage is going? Are there files there? are some missing/not being updated?
