Sizing of NAS backup proxy (file proxy)

Post by phiaramos »

Hello, good day.

I just want to understand how to size up the file proxy or the NAS backup proxy. Correct me if I'm wrong but there's no available sizing calculator for the file proxy requirement, or can we also use https://vse.veeambp.com/ for sizing?

I also saw the formula on https://bp.veeam.com/vbr/2_Design_Struc ... #example-2

"Example 2
50TB source data, 300M files, 2 SMB shares, 3% change rate, eight hours backup window.

*Incremental throughput requirements: (50TB x 3%) / 8 hours = 0.1875TB/h
*1 File Proxy core.
*Files to process per hour: 300M / 8 hours = 37.5M/h
*37.5 / 5 = 7.5 cores
*The highest core count is 7.5

Required file proxies resources are eight cores and 16GB of RAM. These resources must be deployed on a minimum of four proxies (two shares, one proxy task per share) of four cores each. “Normal” and above backup IO control setting can be used."


But I don't understand, how did you get the 5 on the files to process per hour formula to get the number of cores? 37.5 / 5 = 7.5 cores

Hope you can assist me, thank you.

Hello,
I'm not aware of any public calculator, that incorporates the formulas you mention. The result itself is correct (I just put it in Excel)

The "5" is five million files per hour.

Best regards,
Hannes
