What is the cloud (service?) with guaranteed data storage for at least 60 months?

Question

Data storage

Interested in services that will not kill (kill, delete) stored especially important data after a year or two of inactivity. Ie, so that the period of inactivity was prescribed in the terms of use for 60 months.

For:
Google Drive - the period of inactivity is 24 months, then the account can be destroyed.
Protonmail - the period of inactivity is only 3 months.

I would like to have a reliable spare place if I suddenly came out of a coma (pah-pah-pah - in the sense of not getting into it at all) or the time machine went a little crazy and threw it four years ahead without the possibility of returning .

The service must obviously be either well-known or stubborn on the guarantee of storage. To close in two years.
And two services are better - for reservation.

You can even pay - the main thing is that the payment is not monthly (ha ha), but with the possibility of paying for n years in advance.

Update: A friend recommended Amazon S3. It looks interesting right off the bat, but they have only recently introduced the possibility of prepayment and is not yet available to all users. TP requested.

Answer 1

possibly a backblaze

Answer 2

I would not count on the guarantees of such services, they can change the price or other conditions at any time. In addition, there are people working everywhere, and they are constantly making mistakes and can simply lose your data.
But there is good news: in case of loss of your data, you will definitely be given a discount for the next year or a couple of months of free use!
PS Perhaps some decentralized service like FileCoin or Swarm will suit you.
