the case and the solution that replication speed slowed down

[Yuya]

Hello,

When replicating VM over WAN (ex. 100 Mbps), is there anything to be careful about?
Is there a case where replication speed slowed down due to latency?
In addition, please tell me the case and the solution that replication speed slowed down.

Thanks,
Yuya

Hi Yuya,

Surely, low latency can slow down the replication speed. What are the bottleneck stats you see in the UI?

Please correct me if I got your question incorrectly.

Thanks,
Fedor

Hi,

We have not introduced Veeam yet.
We are considering introducing Veeam to replicate via WAN.
However, since the line is thin, we are worried about replication.
Therefore, we would like to know examples of problems that occurred when replicating over the WAN.

Thanks,
Yuya

Hi Yuya,

It's hard to predict what could happen without knowing all the details, but using built-in WAN accelerators is definitely the way to go for the situations when the bandwidth between the locations is low or the connection is unstable. There is a section at our BP portal an official whitepaper covering WAN acceleration capabilities and deployment features - worth checking.

100Mb/s is a quite good speed (if real), and most-likely WAN will not be fully utilized, also leaving some bandwidth for other activities.

Regards,
Fedor

really depends on many factors - number of vms being replicated, how often they need to be replicated (RPOs), is this a true guaranteed 100mbps (e.g. MPLS), what are the SLAs on the circuit, how much of that will be available to veeam replication traffic if hosting other services from the site..
