推荐答案

ASR具有以下优点:

ASR provides the following advantages:

• 应用程序一致的快照频率:默认情况下，站点恢复每4小时拍摄一次应用程序一致的快照.您可以配置1到12小时之间的任何值.应用程序一致的快照 是VM内应用程序数据的时间点快照.卷影复制服务(VSS)可确保在拍摄快照时VM上的应用程序处于一致状态.

• App-consistent snapshot frequency: By default, Site Recovery takes an app-consistent snapshot every 4 hours. You can configure any value between 1 and 12 hours. A app-consistent snapshot is a point-in-time snapshot of the application data inside the VM. Volume Shadow Copy Service (VSS) ensures that app on the VM are in a consistent state when the snapshot is taken.

复制组:如果您的应用程序需要跨多个VM的多VM一致性，则可以为这些VM创建复制组.默认情况下，所选的VM不属于任何复制组.

Replication group: If your application needs multi-VM consistency across VMs, you can create a replication group for those VMs. By default, the selected VMs are not part of any replication group.

点击自定义 复制策略  ;然后选择是以获得多VM一致性，以使VM成为一部分 复制组的名称.您可以创建一个新的复制组或使用一个现有的复制组.选择要作为复制组一部分的VM，然后单击确定.

ClickCustomizenext toReplication policyand then selectYesfor multi-VM consistency to make VMs part of a replication group. You can create a new replication group or use an existing replication group. Select the VMs to be part of the replication group and clickOK.

因此，如果您更改复制中的数据，它将根据您设置的快照频率进行更新.让我知道是否有帮助.可以找到更多信息 此处

So if you change the data in replication, it will update depending on the snapshot frequency you set. Let me know if this helps. more info can be found here
