I have a number of git repos that the original developers deleted - because I sync’d them to a usb stick with gitea. I think that is how you have to do it - never entrust a service, especially a free one, with your only copy of anything you value.
If the YouTube algorithm nukes your account and all your videos, you should be ready to upload them to a new account. Same with anything else digital.
My current is standard is one copy in AWS S3 which is super reliable but too pricy for daily use, and one copy in Cloudflare R2 or Backblaze B2 which might or might not be reliable (time will tell) but is hella cheap for daily use.
