系统数据库复制SQL Server 2008

[英]System database replication SQL Server 2008

What is the best practice in handling DR replication of the system databases? 处理系统数据库的灾难恢复复制的最佳实践是什么?

If the DR server/instance name is different than production is it possible to replicate the MASTER and MSDB databases over? 如果DR服务器/实例名称与生产名称不同,是否可以复制MASTER和MSDB数据库? Or would you need full instance replication at that point? 还是此时需要完整实例复制?

You cannot replicate or mirror the system databases. 您无法复制或镜像系统数据库。

If you use clustering, your system databases live on a shared disk, so they can be brought up on your DR node as clustering provides resilience at the instance level. 如果使用群集,则系统数据库位于共享磁盘上,因此可以在灾难恢复节点上启动它们,因为群集在实例级别提供了弹性。

Backing up the system databases on each server should be sufficient to recover that server in the event of a failure. 在发生故障时,备份每台服务器上的系统数据库应足以恢复该服务器。
