问题描述
Azure恢复服务保管库具有备份配置"设置，以控制保管库的存储复制类型".有2个选项:LRS或GRS存储.对于在Vault中这意味着什么，我需要一些指导.
An Azure Recovery Services Vault has a "Backup Configuration" setting to control the "storage replication type" of the vault. There are 2 options: LRS or GRS storage. I need some guidance on what this means in the context of a vault.
1)当涉及到保管库时，恢复服务保管库的LRS/GRS设置也究竟适用什么?例如，它是否适用于Vault的设置/配置，是否适用于Vault中的任何备份数据?
1) What exactly does the LRS/GRS setting of a recovery services vault apply too when it comes to a vault? For example does it apply to the settings/configuration of the vault, does it apply to any backup data in the vault?
2)如果GRS设置适用于保管库内的备份数据，是否表示在发生灾难时触发故障转移时，保管库内的所有备份数据将可用于辅助区域吗?
2) If the GRS setting applies to backup data within the vault does this mean that in the event of a disaster all backup data within the vault will be made available to a secondary region when a failover is triggered?
3)如果上面的第二点是正确的，那么恢复服务保管库复制的意义是什么?这是否只允许客户在需要时进行故障转移，而不是等待Microsoft启动故障转移?
3) If point #2 above is true what is the point of recovery services vault replication? Does this just allow a customer to failover whenever they want instead of waiting for Microsoft to initiate the failover?
推荐答案
使用GRS作为恢复服务库意味着将您的数据复制到第二个区域.如果主要区域出现故障，您仍然可以使用辅助区域中的此恢复服务库来还原数据.
Using GRS for a recovery service vault means that your data is replicated to a second region. If the primary region goes down you will still be able to restore data using this recovery service vault in the secondary region.
GRS存储故障转移受Microsoft控制，他们将选择何时进行故障转移(尚未发生)，而不是您.客户启动的GRS存储故障转移正在运行预览，但这不会扩展到备份保管库.
GRS storage failover is under the control of Microsoft, they will choose when to failover (which has not happened yet), not you. There is a preview running for customer initiated failover for GRS storage, but this does not extend to backup vaults.
