SQL数据库备份及恢复

备份：

            string Constr = “Provider=SQLOLEDB;Data Source=.;Integrated Security=SSPI;Initial Catalog=数据库名”;//.代表本机

            OleDbConnection myConn = new OleDbConnection(Constr);

            myConn.Open();
            OleDbCommand cmd = new OleDbCommand();
            cmd.Connection = myConn;
            cmd.CommandText = @"backup database  要备份的数据库名 to disk = 'E:\db1.bak '";

            //BACKUP DATABASE [要备份的数据库名] TO  DISK = N'E:\db1.bak' WITH NOFORMAT, INIT,  NAME = N'别名', SKIP, NOREWIND, NOUNLOAD,  STATS = 10

            cmd.ExecuteNonQuery();

            myConn.Close();

 

恢复：

           cmd.CommandText = @"restore database 要恢复的数据库名 from disk = 'E:\db1.bak' with replace";

           //RESTORE DATABASE [要备份的数据库名] FROM  DISK = N'E:\db1.bak' WITH  FILE = 1,  NOUNLOAD,  REPLACE,  STATS = 10
