There also may be a need to another copy of the database contents that can be queried for long-running analytics, that are not fit to be run on the highly transaction-intensive production database. This copy could be a simple restore from the most recent backup on another machine, but the data would be outdated as soon as it is restored.

But now not only has the existence of such a tool been confirmed, we can also test it now. The new Steam Play is basically a modified version of Wine created by Valve, called "Proton", an integrated directly in the Steam client. Proton is an open source project and is available on GitHub.
