Noob who wants to Backup the Cloud

Hey! I saw the post about Google randomly losing a bunch of Google Drive data and I realized that a lot of my data in the cloud can just go away any time and I'd be screwed.

I want to backup my data from numerous cloud services somewhere (either a local hard drive or to some other cloud service, or maybe both?). I'd like to backup Google Drive, Gmail, Notion, GitHub, and Bitwarden.

Are there any recommended tools/services that would allow me to easily backup my data from these services? Or what is the recommended way to go about it? Thanks!
