is efficient and error free.

For this first make references of the following in your app -


codes are follows -

ServerConnection conn;

string subPath = "~/DatabaseBackup";
bool IsExists = System.IO.File.Exists(Server.MapPath(subPath + "\\ConDB.bak"));
if (IsExists) File.Delete(Server.MapPath(subPath + "\\ConDB.bak"));

string databaseName = "mydb";

bkp.Action = BackupActionType.Database;
bkp.Database = databaseName;
bkp.Devices.AddDevice(Server.MapPath(subPath) + "\\ConDB.bak", DeviceType.File);
bkp.Incremental = false;

conn = new ServerConnection(instanceName, userid,password);//put right values of ur server
