Getting off Google is a huge pain in the ass (but of course worth it, and good for you attacking it this year).

I had many hundreds of Gb of photos etc. and Google Takeout is such a mess I ported it all manually via local drive syncs for Google and OneDrive. 

I now have OneDrive sync’d to local removable storage that is my master for everything (I rotate local drives between two locations every couple of years).

I know having cloud storage at all is a concern but it also has a lot of utility for me, I am content knowing it’s not a single point of failure for anything, and that I am locally data-sovereign if they kill the internet.
