准备工作
两台装有的Windows Server 2012R2以及SQL Server 2012的服务器
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
1 USE [master] 2 GO 3 ALTER DATABASE [AdventureWorks2012] SET RECOVERY FULL WITH NO_WAIT 4 GO
对SQL1的AdventureWorks2012进行全备
1 USE [master] 2 BACKUP DATABASE [AdventureWorks2012] TO DISK = N'C:\primaryBackupLog\AdventureWorks.BAK' WITH NOFORMAT, NOINIT, NAME = N'AdventureWorks2012-FullBackup', SKIP, NOREWIND, NOUNLOAD, STATS = 10 3 GO
在SQL2上进行还原,并以STANDBY的方式进行恢复
1 USE [master] 2 RESTORE DATABASE [AdventureWorks2012] 3 FROM DISK = N'C:\secondaryBackup\AdventureWorks.BAK' WITH FILE = 1, 4 MOVE N'AdventureWorks2012_Data' TO N'C:\Program Files\Microsoft SQL Server\MSSQL11.SQL2\MSSQL\DATA\AdventureWorks2012_Data.mdf', 5 MOVE N'AdventureWorks2012_Log' TO N'C:\Program Files\Microsoft SQL Server\MSSQL11.SQL2\MSSQL\DATA\AdventureWorks2012_log.ldf', 6 STANDBY = N'C:\secondaryBackup\AdventureWorks.BAK_S', 7 NOUNLOAD, STATS = 10 8 GO
设置备份选项
