they are not replicated: server(shared) dies: you lose everything.

Traditional backup vendors replicate data (3+ times likely).

They don’t have great North American peering. If you happen to be there and are unlucky, you won’t be able to get a very reliable/fast connection to the server.

I tried to use one for Borg backups a few years ago and just ran into endless transient connection issues.

It's more like $2 a TB in the larger plans. I have 5TB there and it's been working great. I use Borg Backup so the data is all encrypted. If anyone cares, Digital Ocean also makes new customers send their ID.

pCloud offers a 399 EUR lifetime plan for 2 TB of storage, and you can buy this twice or more to add up the capacity.

The catch is the proprietary protocol, supported only by their own app and rclone. WebDAV works on paper, but is too slow to be useful.

For stuff like archive and backup you can use ovh object storage infrequent access. Comes to 5$ per GB but you pay for what you use only and it scale infinitely.
