Why can't I persist data?

[bogdanstate]

I am quite impressed with Prefect, currently playing with it for a project using the Prefect server. I am just starting out so I am not sure if this is a bug or a problem with my understanding of the data model.

So here's what I'm doing:

1. Starting a new prefect server (installed today using conda), and agents, with a dask cluster.
2. Go to GUI, create a new project, let's say "test".
3. Project is successfully created.
4. Trying to stop the server gracefully, by pressing Ctrl+C in the server Terminal window. Then I get the following reply:

^CGracefully stopping... (press Ctrl+C again to force)
Exception caught; killing services (press ctrl-C to force)

Aborted!

5. Restarting the server using prefect server start

My project, and all the state of the Postgres DB is gone. I have a clean slate. This looks less than ideal.

There's a ton of logs that I am getting from the server, so not quite sure what I should look at to diagnose this later.

Hi @bogdanstate the server does not persist data by default and you will have to enable it with a couple extra CLI flags. More information here: https://docs.prefect.io/orchestration/server/deploy-local.html#database-persistence-and-migrations

Thanks, this looks like what I was looking for!
