ASP.NET中備份SQL Server資料庫的方法

下面是我做一個網站後台時在"備份"按扭下寫的一個事件:

protected void Button1_Click(object sender, EventArgs e)

...{

string newname = "WebJake" + DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString() + DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString()+".bak";

SqlConnection cn = DB.createCon();

string nepath=Server.MapPath("http://www.cnblogs.com/DataBack/")+newname;

string sql = "BACKUP DATABASE WebJake to DISK ='"+nepath+"'";

SqlCommand cmd = new SqlCommand(sql,cn);

try

...{

cn.Open();

cmd.ExecuteNonQuery();

HyperLink1.Text = "已成功備份到伺服器路徑：" + nepath+" 請點擊下載到本地！";

HyperLink1.NavigateUrl = "http://www.cnblogs.com/DataBack/"+newname;

HyperLink1.Visible = true;

}

catch (Exception ex)

...{

string exm = ex.Message;

Label1.Text = "備份資料庫出錯，該檔案可能不存在！";

Label1.Visible = true;

}

finally

...{

cmd.Dispose();

cn.Close();

cn.Dispose();

}

當然最關鍵的還是這句:

BACKUP DATABASE WebJake to DISK ='您要儲存的路徑'
