A large cloud for photos - where to get it?

Question

Canon

Good afternoon!
The girl is a photographer-videographer and I want to help her a lot with one question. You need a reliable, well-known, secure, affordable, convenient cloud where you can store photos and videos in different formats. Whatever they were for general access, there was a convenient software for working with the cloud (mac os). already 6 terabytes (three by two) and it becomes scary if the disk flies. It comes out decently for the money, but the reliability is doubtful (you can lose, drop, burn, steal, and so on)
Tell me where do you store your photos in large collections?
Thank you!

Answer 1

https://www.amazon.com/clouddrive/home
https://hubic.com/en/
both have free versions, try before you buy

Answer 2

Home drives are cheaper than the cloud, only if she puts her server somewhere with her hdd, but this is from 100k rubles. The maximum was given like mail.ru per terabyte, but there is dubious reliability.

Answer 3

Of the free ones, there is Flickr, they give 1 TB, you can briefly read my review:
