Is it possible to "download" the archive@blockNumber, and run it locally?

Reposting from the Truffle Discord:
I want to "fork" mainnet at a specific blockNumber. I tried Ganache with Infura, but it rate-limited my requests.

Is it possible to "download" the archive@blockNumber, and run it locally?

Ganache's built-in forking has a higher rate limit than the free versions. It is usually very difficult to hit our limit under normal circumstances.

Also, Ganache does download the state it needs at the specified blockNumber and will reused that state later. However, if the blockNumber changes between runs it has to re-fetch the data all over again.

To add onto this, Ganache's built-in forking can be used by running ganache --fork (to fork mainnet) or ganache --fork ropsten (ropsten can be replaced with another testnet).
