在C＃中自動執行SQL Server備份＃

我在寫一個Windows Forms應用程序來備份我的SQL Server數據庫。我正在使用以下代碼：在C＃中自動執行SQL Server備份＃

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Windows.Forms; 
using System.Data.SqlClient; 

namespace SQL_Server_DB_Backup_and_Restore 
{ 
    public partial class Form1 : Form 
    { 
     private SqlConnection conn; 
     private SqlCommand command; 
     private SqlDataReader reader; 
     string sql = ""; 
     string connectionString = ""; 

     public Form1() 
     { 
      InitializeComponent(); 
     } 

     private void btnBrowse_Click(object sender, EventArgs e) 
     { 
      FolderBrowserDialog dlg = new FolderBrowserDialog(); 

      if(dlg.ShowDialog()==DialogResult.OK) 
      { 
       txtBackupFileLocation.Text = dlg.SelectedPath; 
      } 
     } 

     private void btnConnect_Click(object sender, EventArgs e) 
     { 
      try 
      { 
       connectionString = "Data Source= " + txtDataSource.Text + "; User Id=" + txtUserId.Text + "; Password=" + txtPassword.Text + ""; 
       conn = new SqlConnection(connectionString); 
       conn.Open(); 
       //sql = "EXEC sp_databases"; 
       sql = "SELECT * FROM sys.databases d WHERE d.database_id>4"; 
       command = new SqlCommand(sql, conn); 
       reader = command.ExecuteReader(); 
       cmbDatabases.Items.Clear(); 

       while(reader.Read()) 
       { 
        cmbDatabases.Items.Add(reader[0].ToString()); 
       } 

       txtDataSource.Enabled = false; 
       txtUserId.Enabled = false; 
       txtPassword.Enabled = false; 
       btnConnect.Enabled = false; 
       btnDisconnect.Enabled = true; 

       btnBackup.Enabled = true; 
       btnRestore.Enabled = true; 
       cmbDatabases.Enabled = true; 
      } 

      catch(Exception ex) 
      { 
       MessageBox.Show(ex.Message); 
      } 
     } 

     private void btnDisconnect_Click(object sender, EventArgs e) 
     { 
      txtDataSource.Enabled = true; 
      txtUserId.Enabled = true; 
      txtPassword.Enabled = true; 
      cmbDatabases.Enabled = false; 
      btnBackup.Enabled = false; 
      btnRestore.Enabled = false; 
     } 

     private void Form1_Load(object sender, EventArgs e) 
     { 
      btnDisconnect.Enabled = false; 
      cmbDatabases.Enabled = false; 
      btnBackup.Enabled = false; 
      btnRestore.Enabled = false; 
     } 

     private void btnBackup_Click(object sender, EventArgs e) 
     { 
      try 
      { 
       if(cmbDatabases.Text.CompareTo("")==0) 
       { 
        MessageBox.Show("Please select a database"); 
        return; 
       } 
       conn = new SqlConnection(connectionString); 
       conn.Open(); 
       sql = "BACKUP DATABASE " + cmbDatabases.Text + " TO DISK = '" + txtBackupFileLocation.Text + "\\" + cmbDatabases.Text + "-" + DateTime.Now.Ticks.ToString() + ".bak'"; 
       command = new SqlCommand(sql, conn); 
       command.ExecuteNonQuery(); 
       MessageBox.Show("Database backup is completed successfully"); 
      } 
      catch(Exception ex) 
      { 
       MessageBox.Show(ex.Message); 
      } 
     } 
    }

現在我必須按一個按鈕才能進行備份。我該如何自動化該過程，以便我的應用程序可以每週進行一次備份？

Windows調度程序可以運行你的程序，當你想運行。只需選擇您的exe文件並安排運行時間。在這種情況下，你不需要一個表單應用程序。控制檯應用程序會這樣做。在Main Method中調用您的方法。 – Badiparmagi

以編程方式添加計劃任務的這個問題可能會有用。 http://stackoverflow.com/questions/7394806/creating-scheduled-tasks – scotru

MS SQL Server具有自動執行/調度數據庫備份的功能。在你的對象瀏覽器上。轉至

管理 - >維護計劃 - >新維護計劃
和維護計劃任務拖動備份數據庫任務。
然後點擊上面的日曆圖標設置備份時間。這是針對上面的SQL Server 2008的。
