SQL Server: Add linked server

Today, I delete some rows from a table accidentally,  and the worst is that I didn't backup any databases including log.  

Fortunately, I found a original copy in another sql server, so I added the server link to get the rows back.

IF EXISTS(SELECT * FROM sys.servers WHERE name = N'S1_instance1')
EXEC master.sys.sp_dropserver 'S1_instance1','droplogins'
GO

EXEC sp_addlinkedserver   
   @server=N'S1_instance1', 
   @srvproduct=N'',
   @provider=N'SQLNCLI', 
   @datasrc=N'localhost\MSSQLSERVER,1433';
go


insert into S1_instance1.AdventureWorks2012.Production.ProductCostHistory
Select * from Production.ProductCostHistory
WHERE StandardCost BETWEEN 12.00 AND 14.00
      AND EndDate IS NULL;
PRINT 'Number of rows selected is ' + CAST(@@ROWCOUNT as char(3));
