Those Sony backpacks are (probably, were) something. I had a Vaio backpack that lasted me from ages 17 to 22 as a "daily driver" laptop and general purpose bag, then 22 to 35 as a grocery and travel bag - though if I'm being honest those last few years were more emotional than rational.

Unfortunately no manufacturer information other than Sony on it. :(

If you want an ergonomic backpack that's durable check out Deuter, some of them look a bit ugly but they are very functional.

Currently I use a Raven, it looks nice and I’m hoping that will last long enough I won’t want to carry things on my back by the time it breaks.
