What does NSS mean by consumed capacity?

[TraceyBunyard]

I see that NSS reports against both 'Total Consumed Capacity' (total front-end size of all backup images at the end of each monthly period) and 'Average Consumed Capacity' (total front-end size of all backup images, averaged over a monthly period) but can you give further explanation what this means and how it is worked out please?

That’s correct NSS reports the front end protected space. Below is an example to show you what NSS reports.

If you have a 100GB VM and you run a VMWare full backup with accelerator, assuming that the VM is 50% full, NSS will report 50GB as protected space and 50GB of data will be transferred to the storage medium (the first time the policy runs). The next day the transferred data will drop by as much as 99% but NSS will still report the protected space as 50GB (or very near to that number unless huge changes have taken place) as the backup image supports a full VM restore.

 To clarify there are two viewpoints for charging:

 1. From Veritas to the NSS Customer

This is FETB where you take the largest Image and refers to “data under protection” and ignores extra stored copies retention etc.

2. From the NSS Customer to their Customers/Departments

This is as above but off course now addresses the copies, retention etc. as this is all about Baas and is what is shown in NSS.

 NSS displays 2.

NBU deals with 1.
