嗨 @Nanda

快照存储在Nutanix集群的HDD/SSD盘上。请记住，我们可以在管理程序级别和Nutanix级别上获取快照，这可以提供更好的性能，但在这两种情况下，快照都存储在HDD/SSD磁盘上。

注意，我们还可以使用我们的数据保护特性在不同的集群中远程存储快照，以实现容灾目的。

\r\nSnapshots are stored on HDD\/SSD disks of Nutanix cluster. Keep in mind that we can take snapshot at hypervisor level and also at Nutanix level, which can offer much better performance, but in both cases the snapshots are stored on HDD\/SSD disks.
\r\n
\r\nNote that we can also store snapshots remotely in a different cluster using our data protection features for DR purposes.","quoteUsername":"RichardsonPorto","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

@RichardsonPorto非常感谢。

根据这个视频(链接如下)，当新的数据被写入克隆的/快照的vDisk，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，其中写入了新数据，而基本vDisk是只读的，那么新写入的数据会发生什么?

它将被提交到基本vDisk，还是当前状态快照将处于活动状态，其他快照将被删除?

@RichardsonPorto<\/user-mention> Thank you so much.

\r\nAs per this video(Link below), 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?

实际上没有“提交”的数据做基础磁盘…当你删除一个快照和/或克隆时，该vDisk的block map将被删除，并且任何没有被其他快照和/或克隆使用的extent也将被删除，以释放空间。

例如，在youtube视频从链接，你共享，如果你删除Snap1/Clone1，只有vDisk/块映射将被删除，因为D2和E1区段是由Snap2使用。

\r\nFor instance, on Youtbe video from link that you shared, if you delete the Snap1\/Clone1, only the vDisk\/block map will be deleted, since the extents D2 and E1 are in use by Snap2.","quoteUsername":"RichardsonPorto","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

管理程序级别和nutanix级别的快照之间有什么区别? @RichardsonPorto

问候
