Is there any option for a unlimited cloud storage plan to use with infuse
Are you talking about storage for metadata and settings or for video files to be viewed with Infuse?
Is there any option for a unlimited cloud storage plan to use with infuse for my own tv shows and movies
You can see the current list of cloud services that Infuse works with here
I’d suggest you figure out how much space you really need and check the services available to see what they’d charge. Specifying “Unlimited” will probably get you one of two things, either an enormously expensive option or one that is so slow it wont work for streaming and possibly both.
Is the google one 2tb cloud storage plan enough space for all my tv shows and movies
Depends on how much space your tv shows and movies take. I have no way of knowing what you have as far as library size.
