@ananix<\/user-mention>\u00a0I briefly tested what I thought you are concerned about.<\/p>

I created a PD with CG and added two VM there. Then let it generate several local snapshots.\u00a0and\u00a0removed one of the VMs from it. And waited for the PD to generate more snapshots.<\/p>

I also added the above deleted\u00a0\u00a0entity to a new PD.<\/p>

My observations are:<\/p>

1- Removing Vm from PD (with or without CG) will keep all the old snapshots and you should still have the ability to restore each entity (including he deleted one) from the old snapshots (It allows you to generate a new entity or replace the present one even though the entity it self is not there).<\/p>

2- Even if you remove all the entities from the PD you can still restore them from the PD snapshots.\u00a0\u00a0<\/p>

Hope this helps a little,<\/p>

    你好 @ananix

    您可以参考以下指南，以获取异步DR的深入文档。
    https://portal.nutanix.com/#/page/docs/details?targetId=web-console-guide-prism-v510:wc-protection-domain-wc-c.html

    关于您的最初查询。

    如果要从一致性组中删除任何实体，则可以选择实体，然后单击未保护选定的实体以将其从CG中删除。

    如果要添加实体，请选择实体，将它们添加到新的或现有的CG中，然后单击“保护选择实体”。

    希望这可以帮助 ！

    我确实读过那本书，但最好是描述您如何将实体添加到一致性组中，而不是如何修改它们。
    另外，我也读了https://portal.nutanix.com/#/page/docs/details?targetId=web-console-guide-prism-v510:wc-protection-domain-edomain-edomain-edit-wc-t.html但是，它不涵盖近距离的一致性组，甚至在这里添加或删除……

    我知道如何添加和删除它们，我想知道如何修改它们。
    我从您的答复中了解到，这是不可能的，或者您的意思是我可以在“更新保护域（async dr）：protectiom_domain”中随时随地将它们绕过，然后在单击下一步之前想要吗？
    我不想失去保护域的快照，如果我将其删除并再次添加，我似乎无法找到它对快照的作用。
    但是，也许我对“一致性组”短语的字面意义不够，并且改变一致性组是没有意义的吗？


    也许我应该尝试描述我的场景：
    我有两个保护域，它们混在一起了，我不想使用一致性组，通过向每个实体添加唯一的GC来存档。

    域1
    entity1a：cg = entity1a
    entity1b：cg = entity1b

    域2
    entity2a：cg = entity1a
    Entity2B：CG = Entity1b
    entity2c：cg = entity2c

    我刚刚添加了今天的实体2C，并注意到其他人在与另一个域中的实体共享一致性群体时做错了什么:(

    I did read that one but at the very best it only describes how you add entities to consistency groups not how to modify them.
    In addition I also read\u00a0https:\/\/portal.nutanix.com\/#\/page\/docs\/details?targetId=Web-Console-Guide-Prism-v510:wc-protection-domain-edit-wc-t.html<\/a>\u00a0but it does not cover consistency groups other than in NearSync and even here its about adding or deleting\u2026

    I know how to add and remove them, im wondering how to modify them.
    What I understand from your reply is that it is not possible or do you mean i can shuffle them around in the \u201cUpdate Protection Domain (Async DR): PROTECTIOM_DOMAIN\u201d as much as i want before clicking next?
    I dont wanna lose protection domain snapshots, i cant seem to find out what it does with snapshots if I remove it and add it again.
    But maybe i dont take the \u201cconsistency group\u201d phrase literal enough and it makes no\u00a0sense to change consistency groups??<\/p>


    Maybe i should try and describe my scenario:
    I Have two protection domains and they got mixed up and\u00a0i dont want to use consistency groups, archived\u00a0by adding a unique GC to each entity.<\/p>

    Domain1
    \u00a0 Entity1a:CG=Entity1a
    \u00a0 Entity1b:CG=Entity1b<\/p>

    Domain2
    \u00a0 Entity2a:CG=Entity1a
    \u00a0 Entity2b:CG=Entity1b
    \u00a0 Entity2c:CG=Entity2c

    I just added Entity2c today and noticed the other ones where done wrong as they\u00a0share consistency group with the entities in another domain :(<\/p>","quoteUsername":"ananix","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    @ananix我简要测试了我认为您担心的东西。

    我创建了一个带有CG的PD，并在那里添加了两个VM。然后让它生成几个本地快照。并从中删除了其中一个VM。并等待PD生成更多快照。

    我还将上述已删除的实体添加到新的PD中。

    我的观察是：

    1-从PD中删除VM（有或没有CG）将保留所有旧快照，并且您仍然应该能够从旧快照中还原每个实体（包括他删除一个实体）（它允许您生成新实体或替换即使实体它自我不存在）。

    2-即使您从PD中删除了所有实体，您仍然可以从PD快照中还原它们。

    希望这有所帮助，

    问候，

    像魅力一样工作，您可以随心所欲地兼顾所有历史记录，以及GC继续执行的其他机器。
    不过，要注意的一件事是，更改似乎在单击下一步之前就发生了，因此应该正确避免关闭中期。

    worked like a charm, you can juggle around as much as you want all history stay as is and other machines left in GC\u2019s continue their routines.
    One thing to notice though is that changes seem to take place immediately before clicking next so one should properly avoid closing\u00a0mid-stage.<\/p>","quoteUsername":"ananix","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
