你好，

我希望有人能阐明一些查询我的快照。我的空间低点到目前没有自动化弹性的地步。在使用NCC检查时，我确实会失败。它的值为41，理想情况下应为10。我有3个保护域，总计为127 VM。我每天拍摄快照，但只保留一个副本。即使我只在一个保护域中捕获了50 VM，我也得到了太多快照警报。

- 有人可以解释Snapshot_chain_length实际上是什么以及41来源？
- 快照实际上使用了多少空间？我如何获得此信息（第4.0.1.2号）
- 除了我的一个活动快照外，每个活动的快照还有4个过期的快照。这些实际上占用空间吗？他们的目的是什么？如果我没记错的话，它们不能用于还原。

    \nI was hoping if someone can shed a light on some queries I have re snapshots. I am running low on space to the point where I currently have no autobuild resiliency. I do get a FAIL when it comes to snapshot_chain_length when checking with NCC.The value of that is 41 and ideally should be around 10. I have 3 protection domains with a total of 127 VM. I do a daily snapshot but only retain one copy. I have been getting too many snapshot alerts even when I only had snapped 50 VM in one protection domain.
    \n
    \n-Can someone explain what that snapshot_chain_length actually is and where the 41 comes from?
    \n-How much space is actually used by the snapshots? How can I get this info (NOS 4.0.1.2)
    \n-Each protection domain has 4 expired snapshots in addition to my one active snapshot. Do these actually take up space? What is their purpose? If I am not mistaken they can not be used for restores.","quoteUsername":"AllBlack","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    1. Snapshot_chain_height检查检查检查检查检查检查检查的任何快照链，该链包含25个以上的快照，并报告失败状态，如果它检测到超过25个。

    2.您可以查看Web UI中每个保护域的空间列中使用快照中使用的空间。

    3.就过期的快照而言，它们确实占用空间，对于每个保护域，默认设计可保留5个过期的快照，因此将存在5个过期快照，直到第六个出现并删除操作删除，最古老的快照。这样做是为了使客户想使用旧快照。可以更改此设置，但为此，我建议您在进行这些更改之前打开带有Nutanix支持的票。

    \n2. You can check the space used column for each protection domain in Web UI for space used in snapshots.

    \n3. As far as expired snapshots is concerned, they do take up space and for each protection domain, there is a default design of keeping 5 expired snapshots, so there will be 5 expired snapshots present until the 6th one shows up and delete operation deletes the oldest snapshot. This was done in case customer wants to use the old snapshots. This setting can be changed but for that I would suggest you to open up a ticket with Nutanix support before making these changes.","quoteUsername":"DonnieBrasco","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
