每当我采取快照棱镜中心，它显示在恢复点，但不在快照。不确定，两者是否相同。

此外，恢复点提供了一个“复制”选项，而快照提供了一个“恢复”....选项都是一样吗?

Hi @Charu<\/user-mention>\u00a0<\/p>

VM Recovery Point is a Snapshot effectively, you are not wrong here.<\/p>

A Snapshot can be triggered manually or by a schedule in PE. It can also be replicated to a remote site as part of the Protection Domain.<\/p>

A Recovery point is a similar thing in that it is a snapshot, it is stored locally on the cluster and can be replicated to a remote cluster as part of a Protection Domain. Recovery Point can be created manually or be handled by a Protection Policy configured in PC. A VM can be restored from a Recovery Point either locally or remotely in a state of a chosen recovery point. This is effectively the same as the Clone from a Snapshot in that you are creating a copy of a VM as it was at a certain point in time in the past.<\/p>

Let\u2019s level up the complexity now.
A Snapshot is a PE\/AHV term. PC can detect a Snapshot and can restore\/delete a Snapshot but it can\u2019t create a Snapshot.<\/p>

Recovery Point is a PC term. PE is not even aware of such a thing. Moreover, if a VM is part of a Protection Domain \u201cCreate Recovery Option\u201d is greyed out in PC.<\/p>

To summarise, both an AHV Snapshot and PC Recovery point are technically the same technology while a Recovery Point is a construct that is operated by Prism Central.Happy to answer any further questions.<\/p>","className":"post__content__best_answer"}">

Whenever I take snapshots from Prism Central it shows under Recovery point but\u00a0not under Snapshot. Not sure, if both are same Thing.<\/p>

Also, recovery point give an option to \u201cReplicate\u201d , whereas Snapshot give an option to \u201cRestore\u201d\u2026.are both same?<\/p>","quoteUsername":"Charu","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嗨 @Charu

复制和恢复是两个不同的东西，当我们想回滚到某个时间点的副本时，我们通常会做恢复，而复制就像保护某个副本到另一个站点/容灾。

恢复存储在本地，恢复点存储在其他站点/灾备站点

Hi @Charu<\/user-mention>\u00a0<\/p>

Replicate and Restore are 2 different things, we generally do restore when we want to rollback to a certain point in time copy whereas replication is like protecting certain copy to another site \/DR .<\/p>

Restore are stored locally while the Recovery points are stored in another site\/DR site<\/p>","quoteUsername":"Neel Kotak","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

恢复—用过去的快照替换当前的虚拟机，也就是将虚拟机回滚到以前的状态。复制—正在拷贝前一状态的虚拟机。

Restore <\/strong>- this is replacing the current VM with a snapshot from the past, aka rolling it back to a previous state. Replicate <\/strong>- You are making a copy of the VM in the previous state.<\/p>","quoteUsername":"bdiener","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嗨Charu

我猜这是恢复点和快照之间的区别，因为自助服务门户，但我也在寻找一个解释。

我的想法是，只允许访问SSP的用户创建他们可以恢复的恢复点，而不允许恢复可能用于Replication的快照。如果你要求支持或得到了一个明确的答案，请让我知道。

Hi Charu<\/p>

I guess it makes a difference between recovery points and snapshots because of the Self Service Portal, but I\u00a0am searching for an explanation on that too.<\/p>

My belief is that users with access to the SSP only can just\u00a0be permitted to create recovery points to which they can restore and not restore the snapshots which might be done for Replication. If you asked the support or got an answer to that which makes it clear, please let me know.<\/p>","quoteUsername":"ChristopherC","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嗨 @Charu

虚拟机恢复点实际上就是一个快照，你没有错。

快照可以手动触发，也可以通过PE中的调度触发。还可以将其作为保护域的一部分复制到远程站点。

“恢复点”与“保护域”类似，它是一种快照，存储在集群本地，可以作为保护域的一部分复制到远端集群。恢复点可以手动创建，也可以通过PC上配置的保护策略来处理。虚拟机可以从本地恢复，也可以从远程恢复，恢复状态为所选恢复点。这实际上与从快照克隆相同，因为您创建的是虚拟机在过去某个时间点的副本。

现在让我们提升复杂性。
快照是PE/AHV术语。PC可以检测到快照，可以恢复/删除快照，但不能创建快照。

恢复点是一个PC术语。体育甚至不知道这样的事情。当虚拟机属于保护域时，PC上的“创建恢复选项”显示为灰色。

总之，AHV快照和PC恢复点在技术上是相同的技术，而恢复点是一个由Prism Central操作的构造。乐意回答任何问题。

嗨 @Alona，有没有一种方法可以得到所有通过棱镜中心创建的恢复点的列表。

Hi\u00a0@Alona<\/user-mention>\u00a0, is there a way to get list of all the Recovery Points created through Prism Central.<\/p>","quoteUsername":"Charu","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

@Alona我明白了，我们可以在PC ->虚拟基础设施->可恢复实体中得到详细信息。谢谢:)

@Alona<\/user-mention>\u00a0I see, we can get the details in PC ->Virtual Infrastructure->Recoverable Entities. Thanks :)<\/p>","quoteUsername":"Charu","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
