Compression Level in the report of job replica

[gedossou]

Hello,
I'm doing replica job tests on Veeam to evaluate the best compression level (None, Friendly, High, and Extreme).
However in my job replica report, I always in column Compression the value 1.0X regardless of the chosen compression level.
Could you please explain me or there would be another way to use this feature ?
How do I know that the chosen compression level has worked in my replica job?

Thank you

Hello!

Replicas are store in native uncompressed format, which is why you're seeing 1.0x
For replication jobs, this setting is used for network traffic compression only.

Thanks!

Thanks Gostev !

Hello Gostev

However, if I understand correctly, this Compression Level feature
does not act on the virtual machine data to be backed up
but on the compression of network traffic.
Question 1: What is the impact on network traffic when I choose:
- None,
- Friendly
- High
- Extreme
Question 2: Should the Compression feature be used in parallel with Storage Optimization?
Thx

Yes, that's correct.

Question 1: What is the impact on network traffic when I choose:

- Friendly
- High
- Extreme

I would say that impact is more on the proxy server which compresses the data, thus use more CPU cycles.

Question 2: Should the Compression feature be used in parallel with Storage Optimization?

Yes, but these are independent settings. Please take a look at this post from foggy for more info.

The impact is respective to the compression level. For example, no compression means your bandwidth usage will be equal to the VM size (and size of changes during incremental runs). While extreme compression will reduce most network traffic significantly. And other two settings are somewhere in between. Some of the information on how compression levels compare to each other can be obtained right from the UI labels below the selected compression level. Thanks!
