Number of proxy tasks / slots

Hi All.

I've been doing some research on sizing recently using the best practices guide and Timothy Dewin's "Sizing the Beast" webinar. Both mention that you should size for 1 proxy slot (1 core/vCPU and 2GB RAM) for every 30 VMs to be backed up in an 8 hour window. This seems to be based on an average size of 100GB per VM.

If this is so, would it be fair to say that the guidelines are ultimately based on each slot being able to process about 3TB (30 x 100GB) of data in an 8 hour window?

Thanks,
Neil.

There are many ways to calculate proxy and repository ressources... by throughput, time and others. The 30-40VMs per Core and 8h backup window came from observation of existing customers and it worked way more reliable then any other method. Storage Systems are so different when it comes to random read and write.

The calculation is done that way that it is unlike that the proxy or repository role is the bottleneck at incremental forever runs.
