BGSAVE
Save the DB in background. The OK code is immediately returned. Redis forks, the parent continues to serve the clients, the child saves the DB on disk then exits. A client may be able to check if the operation succeeded using the LASTSAVE command.
Please refer to the persistence documentation for detailed information.
