你好

我有一个有关VM快照的问题。我认为这是不可能的，否则我确定这在PE或PC中会很明显，但我还是会问：

我们可以快照VM的活动内存吗？即，在快照中包括活动OS内存，等效于ESXI的.VMEM文件

我已经阅读了Crash vs应用程序一致的快照，但我看不到捕获OS内存的提及

谢谢

Hi<\/p>

I have a\u00a0question about VM snapshots.\u00a0 I dont think this is possible otherwise I\u2019m sure it would be obvious in PE or PC but I\u2019ll ask anyway:<\/p>

Can we snapshot the VM\u2019s active memory?\u00a0 i.e. include the active OS memory in the snapshot, the equivalent of ESXI\u2019s .vmem file<\/p>

I\u2019ve read up on crash vs application consistent snapshots but I dont see a mention of capturing the OS memory<\/p>

Thanks<\/p>","quoteUsername":"MWStu","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

你好 @mwstu

默认情况下，VM快照是频率一致的，这意味着捕获的VDisks与单个时间点一致。快照表示盘数数据，好像VM崩溃或从服务器中拉出电源线一样，它不包含在拍摄快照时内存中的任何内容。如今，大多数应用程序可以使用碰撞一致的快照恢复。

应用程序一致的快照捕获与碰撞一致的快照相同的数据，随着记忆中的所有数据和过程中的所有交易。由于其额外的内容，符合应用程序的快照是最参与的，并且要花时间最长。

Hello @MWStu<\/user-mention>\u00a0<\/p>

VM snapshots are by default crash-consistent, which means that the vDisks captured are consistent with a single point in time. The snapshot represents the on-disk data as if the VM crashed or the power cord was pulled from the server\u2014it doesn't include anything that was in memory when the snapshot was taken. Today, most applications can recover well using crash-consistent snapshots.<\/p>

Application-consistent snapshots<\/strong> capture the same data as crash-consistent snapshots, with the addition of all data in memory and all transactions in process.<\/strong> Because of their extra content, application-consistent snapshots are the most involved and take the longest to perform.<\/p>","quoteUsername":"Moustafa Hindawi","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
