前言:我們?cè)陂_(kāi)發(fā)網(wǎng)站時(shí),在管理后臺(tái),管理員通常要定期對(duì)數(shù)據(jù)庫(kù)進(jìn)行備份(當(dāng)然也可以讓sqlserver服務(wù)器定期自動(dòng)備份,但我此處講的是asp.net中的備份),備份的代碼很簡(jiǎn)單:

下面是我做一個(gè)網(wǎng)站后臺(tái)時(shí)在"備份"按扭下寫的一個(gè)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("../../DataBack/")+newname;

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

SqlCommand cmd = new SqlCommand(sql,cn);

try

...{

cn.Open();

cmd.ExecuteNonQuery();

HyperLink1.Text = "已成功備份到服務(wù)器路徑：" + nepath+" 請(qǐng)點(diǎn)擊下載到本地！";

HyperLink1.NavigateUrl = "../../DataBack/"+newname;

HyperLink1.Visible = true;

}

catch (Exception ex)

...{

string exm = ex.Message;

Label1.Text = "備份數(shù)據(jù)庫(kù)出錯(cuò)，該文件可能不存在！";

Label1.Visible = true;

}

finally

...{

cmd.Dispose();

cn.Close();

cn.Dispose();

}

當(dāng)然最關(guān)鍵的還是這句:

BACKUP DATABASE WebJake to DISK ='您要保存的路徑'
