Another factor complicating the assessment is the fact that long term archival technology options, tape, WORM, has not kept pace with platter densities. There was a time (long ago), when you could easily back up your entire system to helical scan tape or optical media.
Today, even though there has been advances in low-cost optical storage densities (blu-ray), it still would take 120+ Blu-Rays to store a single 6TB hard hard drive. There are of course higher density solutions with automated jukeboxes, but they can be pricey.
So the easiest option is to use drives to backup other drives and use more drives instead of archiving to a long term media. But it gets expensive for the longer retention periods.

Not directly related to this but we advise customer who are willing to invest more in cameras to buy analytic cameras (like the Avigilon H3A) and save a lot on storage.
This does not apply to indoor cameras but for outdoor they save a LOT of storage.

In Avigilon at least, the H3A cameras come with motion detection disabled.
You have classified object motion detection which mean that the NVR will record only when Humans or cars are detected.
This means that all other (non interasting) motion detection events are not recorded.
From the cameras we have installed here outside of our office for show we see a great reduction in recrod time as at night there is virtually no recording and at day time its also minimized.
As I wrote this does not apply to indoor cameras as they do not differ much from analytic cameras.

We have done this when we fist installed the camera and done this for customers pilot testing.
The results are:
