When starting ganache-cli, you can specify the flag --db /path/to/db which creates the DB directory if it doesn't exist and save the blockchain state. So when you restart ganache with the same flag, it initializes the blockchain from this state.

ganache-cli --db /path/to/db/

Extract from documentation:

--db: Specify a path to a directory to save the chain database. If a database already exists, ganache-cli will initialize that chain instead of creating a new one.

  • Sorry didn't get that. --db stores the entire blockchain states (transactions, accounts balances, smart contract states, etc...) – Greg Jeanmart Dec 12 '18 at 10:42
