你好，我总是被照顾得很好。

我使用CloudConnect通过VPN连接到AWS，并启用NW压缩。
每天重复这一点。
从一年前开始，所有的pd都失败了。下面是关于棱镜的信息;
---

快照(X,X,X)的保护域XXXX跳过复制到远端站点XXX。由于有较新的快照可用，复制被跳过。

---

我在CVM上执行cli，复制状态是“发送”。

---

美元ncli pd list-replication-status

复制操作:发送

我在“棱镜”上做的“连接测试”是“OK”。

你认为这个原因是什么?

真诚地,

Hi @Sayo<\/user-mention>\u00a0<\/p>

This alert is triggered when there is\u00a0a newer snapshot\u00a0present on the cluster than the one that is used to replicate the current PD. This alert that gets generated while replication is in progress is a valid condition and will hold true when the replication is slow.
If replication becomes slow and the subsequent newer snapshots are available this alert\u00a0is generated.\u00a0\u00a0KB-4282<\/a><\/p>

I guess in this case if the snapshot size is bigger or if the network bandwidth is slow during that time then there are chances existing replication gets slow and\u00a0in the meantime, a newer snapshot is generated. If\u00a0this is happening frequently then you can either increase the network bandwidth or increase the time duration between two snapshots.<\/p>

Hi, I am always taken care.<\/p>

\u00a0<\/p>

I use CloudConnect by VPN connection to AWS and enable NW compression.
Everyday repeat that.
Since 1 year ago, All PDs are failed. below the message on Prism ;
---<\/p>

Replication was skipped for protection domain XXXX of snapshot (X,X,X) to remote site XXX. Replication was skipped as a newer snapshot was available.<\/p>

---<\/p>

I executed cli on CVM, replication statuses\u00a0are \u201cSending\u201d\u00a0.<\/p>

---<\/p>

$ncli pd list-replication-status<\/p>

\u00a0Replication Operation\u00a0\u00a0\u00a0\u00a0 : Sending<\/p>

\u00a0<\/p>

And I did\u00a0\u201cTest Connection\u201d on Prism was \u201cOK\u201d.<\/p>

\u00a0<\/p>

What do you think this reason?<\/p>

\u00a0<\/p>

嗨 @Sayo

当集群中存在比用于复制当前PD的快照更新的快照时，将触发此警报。复制正在进行时生成的此警报是一个有效的条件，当复制速度较慢时将保持为真。
如果复制变慢，并且有后续更新的快照可用，则生成此警报。kb - 4282

我猜在这种情况下，如果快照大小更大，或者在此期间网络带宽变慢，那么现有的复制可能会变慢，同时生成一个新的快照。如果这种情况经常发生，那么您可以增加网络带宽或增加两个快照之间的时间间隔。

嗨

跳过复制意味着在完成第一个快照复制之前，我们还有第三个快照要复制。在本例中，我们将跳过第二个步骤，直接复制第三个步骤

不会有数据丢失，但是远程站点上不会有快照2

Hi<\/p>

Skipped replication means we had a 3rd\u00a0\u00a0snapshot to replicate before the 1st snapshot replication finished. In this case we will skip the 2nd one and directly go to replicate the 3rd one \u00a0<\/p>

\u00a0<\/p>

There will be\u00a0no data loss but you will not have snapshot 2 on the remote site\u00a0<\/p>","quoteUsername":"Paul Ilavarasu","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

非常感谢您的回复。

我对AsyncDR规范的理解。

Thank you so much for your reply.<\/p>

I understood to specification of AsyncDR.<\/p>
