hoe kan ik een back-up maken en de datum herstellen vanuit de mysql-database?

import java.io.IOException;

public class DatabaseManager {  

public static boolean backup(String mysqldumpPath, String backupPath) {
    boolean status = false;
    String username = "name";
    String password = "pword";
    String database = "database_name";


    String command = "/" + mysqldumpPath + "/mysqldump -u " + username + " -p" + password + " " + database + " -r " + backupPath;
    try {
        Process runtimeProcess = Runtime.getRuntime().exec(command);
        int processComplete = runtimeProcess.waitFor();
        if (processComplete == 0) {
            System.out.println("DatabaseManager.backup: Backup Successfull");
            status = true;
        } else {
            System.out.println("DatabaseManager.backup: Backup Failure!");
        }
    } catch (IOException ioe) {
        System.out.println("Exception IO");
        ioe.printStackTrace();
    } catch (Exception e) {
        System.out.println("Exception");
        e.printStackTrace();
    }
    return status;
}
public static boolean restore(String filePath){
    boolean status = false;
    String username = "name";
    String password = "pword";
    String[] command = new String[]{"mysql", "database_name", "-u" + username, "-p" + password, "-e", " source "+filePath };

    try {
        Process runtimeProcess = Runtime.getRuntime().exec(command);
        int processComplete = runtimeProcess.waitFor();
        if (processComplete == 0) {
            System.out.println("DatabaseManager.restore: Restore Successfull");
            status = true;
        } else {
            System.out.println("DatabaseManager.restore: Restore Failure!");
        }
    } catch (IOException ioe) {
        System.out.println("Exception IO");
        ioe.printStackTrace();
    } catch (Exception e) {
        System.out.println("Exception");
        e.printStackTrace();
    }
    return status;
}

//for testing
public static void main(String args[]){
    String backupName = "D:/DatabaseBackup/backupHvs.sql";
    DatabaseManager.restore(backupName);
}

}
