Sizing for NAS/file share backup can appear difficult initially, but with the help of the unofficial NAS Calculator by Hal Yaman it definitely will be a bit easier.

As you can see from the screenshot below you need to know roughly how much source data in TB your file share(s) contain, how many files and directories.

 

In case you are wondering what is primary vs secondary repository? Primary is for your short term retention (newest version) and secondary is for long term retention (older versions than newest).

The user guide has some good info on the secondary copy settings.

Once you have filled all out, just click the Calculate button to get full sizing for all components:

  • Cache repository
  • File Proxy
  • Primary repository
  • Secondary Repository

Hope this was useful and please do post any questions or comments.

excellent information, did not know this site :clap:


Awesome! Just the answer I needed to a student question.


@erwanns could be useful for courses :grin:


@haslund : This is indeed a good information !


Nice, I was looking for some like that.


Another great resource.  Bookmarked!!


Also bookmarked 😉 !


Didn’t see this post initially. Nice resource Rasmus!


I’m looking at a significant amount of NAS Backup VUL’s as we speak. This will be helpful. Thanks


In addition to the Veeam calculators, Object first has created calculator for NAS backups to object storage.

Just a quick note for any still following this thread. The calc posted at the top of the thread is from 4+ years ago. While it was an amazing effort at the time (great work Hal), the software has advanced dramatically since then, with numerous efficiency improvements and capabilities. 

Veeam can’t (and wouldn’t) stop others developing their own calculators, and we see plenty of folks still using their old spreadsheets. I will point out that the only official calculator (for Veeam) is on veeam.com. The formulas and calculations go through Veeam employees, Veeam architects, Veeam QA and Veeam PM. This is now the source that informs the BPG, the VMCA, sessions at VeeamOn etc.

I won’t pretend it’s infallible (the big green button says ‘Estimate’ after all), but the results are not only validated by QA testing, but also anecdotally across hundreds of customer deployments of varying sizes, storage types, and workload types including NAS.

Hope that helps.

This new calculator has made my job much easier when delivering VMCA courses.


Great

One important thing to consider when using NAS the calculator is the amount of files, the more files on the NAS, the more resources will be used, so if you don't know the amount of files on your NAS, use an application such as treesize to get this number or if your NAS reports this value, use it.
