为了确保数据的安全，我们往往要对数据进行备份。但是为了减少我们的工作量，我写了一个简单的数据备份工具，实现定时备份数据库。

其实程序很简单，数据备份的工作就是几个mysql的命令而已。

先看看程序的运行界面

可以看到界面是十分的简单的

我们使用的是命令行来进行数据备份，所以我们的程序需要一个能够执行命令行的函数

/// <summary>
        /// 执行Cmd命令
        /// </summary>
        /// <param name="workingDirectory">要启动的进程的目录
        /// <param name="command">要执行的命令
        public static void StartCmd(String workingDirectory, String command)
        {
            Process p = new Process();
            p.StartInfo.FileName = "cmd.exe";
            p.StartInfo.WorkingDirectory = workingDirectory;
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardInput = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.CreateNoWindow = true;
            p.Start();
            p.StandardInput.WriteLine(command);
            p.StandardInput.WriteLine("exit");
        }

接下来是一个备份数据库的函数

public void bakup_db()
        {
            try
            {
                //String command = "mysqldump --quick --host=localhost --default-character-set=gb2312 --lock-tables --verbose  --force --port=端口号 --user=用户名 --password=密码 数据库名 -r 备份到的地址";
                //构建执行的命令
                StringBuilder sbcommand = new StringBuilder();

                StringBuilder sbfileName = new StringBuilder();
                sbfileName.AppendFormat("{0}", DateTime.Now.ToShortDateString()).Replace("-", "").Replace(":", "").Replace(" ", "").Replace("/", "");
                String fileName = sbfileName.ToString();
                String directory = bakpath + fileName+".bak";

                sbcommand.AppendFormat("mysqldump --quick --host=localhost --default-character-set=utf8 --lock-tables --verbose  --force --port=3306 --user={0} --password={1} {2} -r \"{3}\"", uname, upass, dbname, directory);
                String command = sbcommand.ToString();

                //获取mysqldump.exe所在路径
                //String appDirecroty = System.Windows.Forms.Application.StartupPath + "\\";
                StartCmd(appDirecroty, command);
            }
            catch (Exception ex)
            {
            }
        }

还原数据库

 public void recovery_db()
        {
            //string s = "mysql --port=端口号 --user=用户名 --password=密码 数据库名<br>
为了实现定时备份，我们使用的是一个Timer组件，来实现定时的数据备份


<pre class="brush:php;toolbar:false">private void timer1_Tick(object sender, EventArgs e)
        {
            int h = DateTime.Now.Hour;
            if (h == hour)
            {
                bakup_db();
            }
        }
