准备工作

两台装有的Windows Server 2012R2以及SQL Server 2012的服务器

下载评估版 Windows Server 2012 R2

下载 Microsoft SQL Server 2012 SP1

两台机器可以相互Ping 通，测试环境为了不必要的麻烦请关闭Windows 防护墙

IP:192.168.100.101 Servername: SQL1\SQL1

IP:192.168.100.102 Servername: SQL2\SQL2

开始SQL Server 代理服务 并设置为自动开启

SQL Agent 登入设置:在服务管理中改成使用Administrator，如自建用户请确保两边用户名以及密码相同。并启动服务。

准备共享文件夹

事务日志传送的就是由主库不断产生事务日志文件的备份（或者叫归档日志，可能更好理解）而备库不断还原这些事务日志备份文件的过程。

中间需要一个文件夹作为双方的访问的共享文件夹。

如果这个共享文件夹位于主库的服务器上，主库的备份路径可以不写成UNC路径的形式，而备库则必须写成UNC路径的形式。

如果这个共享文件夹位于备库的服务器上，主库的备份路径就要写成UNC路径，而备库可以写成本地路径的形式。

如果共享文件夹即不在主库也不在备库的服务器上面，那么备份、还原目录的名称都要写成UNC路径了。

在SQL1的C 盘创建一个名为primaryBackupLog的文件夹，并设置为共享文件夹。 NUC:\\SQL1\primaryBackupLog

在SQL2的C 盘创建一个名为secondaryBackup

SQL Server 请使用SQL Server账号进行登录的，

UserName：sa Password 相同

测试环境为了不必要的麻烦，请使用Administrator账号

将SQL1的 AdventureWorks2012 恢复模式改为完整

 USE [master]
 GO
 ALTER DATABASE [AdventureWorks2012] SET RECOVERY FULL WITH NO_WAIT
 GO

对SQL1的AdventureWorks2012进行全备

 USE [master]
 BACKUP DATABASE [AdventureWorks2012] TO  DISK = N'C:\primaryBackupLog\AdventureWorks.BAK' WITH NOFORMAT, NOINIT,  NAME = N'AdventureWorks2012-FullBackup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10
 GO

在SQL2上进行还原，并以STANDBY的方式进行恢复

 USE [master]
 RESTORE DATABASE [AdventureWorks2012]
 FROM  DISK = N'C:\secondaryBackup\AdventureWorks.BAK' WITH  FILE = 1,
 MOVE N'AdventureWorks2012_Data' TO N'C:\Program Files\Microsoft SQL Server\MSSQL11.SQL2\MSSQL\DATA\AdventureWorks2012_Data.mdf',
 MOVE N'AdventureWorks2012_Log' TO N'C:\Program Files\Microsoft SQL Server\MSSQL11.SQL2\MSSQL\DATA\AdventureWorks2012_log.ldf',
 STANDBY = N'C:\secondaryBackup\AdventureWorks.BAK_S',
 NOUNLOAD,  STATS = 10
 GO

设置备份选项
