db.fsyncLock()

Forces the mongod to flush all pending write operations to the disk and locks the entire mongod instance to prevent additional writes until the user releases the lock with the db.fsyncUnlock() command. db.fsyncLock() is an administrative command.

This command provides a simple wrapper around a fsync database command with the following syntax:

{ fsync: 1, lock: true }

This function locks the database and create a window for backup operations.
