Nutanix快照

请帮忙：



根据此视频，当新数据写入克隆/快照的VDisk时，当我们删除快照时会发生什么？假设我们创建了三个快照，并删除了第二个快照，该快照仅在读取基本VDISK时编写了新数据，新书面数据会发生什么？



它会致力于基本VDISK还是当前状态快照将还活着，而其他状态快照将被删除？

\r\nAs per this video, when the new data is written to the cloned\/snapshotted vDisk, what happens when we delete a snapshot? Say we created three snapshots and deleted a second snapshot which have new data written while the base vDisk was read only, what happens to the newly written data?

\r\n

\r\nWill it be committed to the base vDisk or the current state snapshot will be alive and other will be deleted?

@nanda

对延迟答复表示歉意。您问题的答案是：除非您选择删除VM的所有快照，否则将不会提交对基本磁盘的更改。

请让我知道是否可以回答您的问题。

@Nanda<\/user-mention>\u00a0<\/p>

Apologies for the delayed reply. The answer to your question is: unless you choose to delete all snapshots for the VM, changes to the base disk will not be committed.<\/p>

Please let me know if that answers your question.<\/p>","quoteUsername":"Alona","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

@nanda在提到的顶部 @Alona

假设我们创建了三个快照，并删除了第二个快照，该快照仅在读取基本VDISK时编写了新数据，新书面数据会发生什么？

在删除第二个快照之前一切 ”新写”有关的数据将是第三快照继承并将在上面使用；因此，删除第二个快照不会删除不仅读取的任何新数据。

但是第二快照上的旧数据是”覆盖”第三个快照将是丢失的（永远，如果你不要删除第二个快照的克隆）。

如前所述，当所有快照被删除时，所有数据都将投入到基本磁盘上

希望这进一步阐明。

@Nanda<\/user-mention>\u00a0 On the top of what was mentioned by\u00a0@Alona<\/user-mention>\u00a0<\/p>

Say we created three snapshots and deleted a second snapshot which have new data written while the base vDisk was read only, what happens to the newly written data?<\/p> <\/blockquote>

Before you remove the second snapshot<\/strong>\u00a0all the \u201cnewly written<\/strong>\u201d data on it will have been inherited by the third snapshot<\/strong>\u00a0and will be available on it; \u00a0so deleting the second snapshot won\u2019t delete any new data that was written on it when it was not read only.<\/p>

But\u00a0the old data on the second snapshot where they were \u201coverwritten<\/strong>\u201d on the third snapshot will be lost<\/strong> (forever, if you do not<\/strong> take a clone of the second snapshot before deleting it).\u00a0<\/p>

And as was mentioned, all data will be committed to the base disk when all the snapshots are removed<\/p>

Hope this clarifies further.<\/p>
