Does anyone know what my options are for redundancy using SQL Server 2008 Express edition. 有谁知道我使用SQL Server 2008 Express版实现冗余的选择。 I'm looking to have 2 DB servers running the express edition. 我希望有2个运行Express Edition的数据库服务器。

3 个解决方案

The normal options here are Replication or Mirroring . 此处的正常选项是复制或镜像。 Express Edition supports neither of those (note the footnotes for the replication entries). Express Edition不支持这两种格式（请注意复制条目的脚注）。 I guess the idea is that if your organization cares enough to do it and can afford two boxes for DB redundancy, it can afford a for-pay Sql Server as well. 我想这个想法是，如果您的组织足够在意它，并且可以提供两个用于DB冗余的设备，那么它也可以提供有偿的Sql Server。

Do you want high availability or disaster recoverability? 您想要高可用性或灾难可恢复性吗？

For HA there aren't that many options since Express does not support any HA feature (ie. failover of any kind). 对于高可用性，由于Express不支持任何高可用性功能（即任何类型的故障转移），因此没有太多选择。

For DR you can set up Log Shipping manually. 对于灾难恢复，您可以手动设置日志传送。 Although you're missing the log shipping agents, is not rocket science to set up a couple of service jobs to backup the log, copy the files and the apply the logs on your DR site. 尽管您缺少日志传送代理，但要设置几个服务作业来备份日志，复制文件并在您的灾难恢复站点上应用日志并不是火箭科学。 The original Log Shipping was nothing more than a few .bat scripts put together by MS customer support. 原始的日志传送只不过是MS客户支持放在一起的几个.bat脚本。

The Express edition of MS products have two purposes. MS产品的Express版本具有两个目的。 First, they allow new developers a way to get familiar with the microsoft stack without a financial investment. 首先，它们允许新开发人员无需花钱就可以熟悉Microsoft堆栈。

Second, they are geared towards small non-mission critical apps. 其次，它们面向小型非任务关键型应用程序。 It's kind of like peeing in your wetsuit. 这有点像在潜水衣里撒尿。 Sure you can do it, but would you really want to? 当然可以，但是您真的要这么做吗？
