does someone have experience with Prefect Disaster Recovery? What are the best practices to restore the workflow and also the history of the runs?

This question is timely, we've released that just today! https://prefect-community.slack.com/archives/CKNSX5WG3/p1661800811845989 If you have more questions about it, you can reach out to sales@prefect.io

thanks @Anna Geller I'm also wondering if one Admin goes rogue and deletes everything ... how can I recover from that?

Since this is an Enterprise feature, I'd encourage you to reach out to sales@prefect.io or cs@prefect.io - there are definitely ways to solve that and customize this setup to your needs
