I have an older Mac Power Book (15 years old) that I still use now and again and it is old enough that it won’t ‘update’ anymore but still has connectivity and I use it for some of my old projects and just for fun.
Anyway, I got an email from Koingo (https://www.koingosw.com/) a third party software developer that I’ve got some apps from – he lost tons of video and pictures from his cloud account and is warning people to back up cloud data ASAP. There is more information at the company website. This may not impact a lot of people but this is a good example of needing backup data.
