as a software developer myself, I agree that you should keep several technologies to backup your data
the cloud can and did fail for me; for maybe three years I could not access around 1500 tunes I had bought on iTunes; no explanation, no help
when they became available again I immediatly bought an Ipod touch and downloaded everything to it
SSD drives can and did fail for me and a couple of other persons; the main drive on these laptops just died, even expensive ones
2 TB HDDs are far from useless and still cost around 100 euros each
I have 5 of them since I first bought BIAB audiophile in 2016
If for some reason my 2021 BIAB fails I still can work with a previous version until the disk is replaced with a new one
If you write anything of value like lyrics you should also have several copies on paper
