.NET中备份SQL Server数据库的方法

前言:我们在开发网站时,在管理后台,管理员通常要定期对数据库进行备份(当然也可以让sqlserver服务器定期自动备份,但我此处讲的是asp.net中的备份),备份的代码很简单:

下面是我做一个网站后台时在"备份"按扭下写的一个事件:

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 = "已成功备份到服务器路径：" + nepath+" 请点击下载到本地！";

hyperlink1.navigateurl = "../../databack/"+newname;

hyperlink1.visible = true;

}

catch (exception ex)

...{

string exm = ex.message;

label1.text = "备份数据库出错，该文件可能不存在！";

label1.visible = true;

}

finally

...{

cmd.dispose();

cn.close();

cn.dispose();

}

当然最关键的还是这句:

backup database webjake to disk ='您要保存的路径'
