Never worry about backups or lost data etc, as the provider would take care of it

This is not how it works. You still have to backup your data!

Your account can be closed due to various reasons, you accidentally delete files, some malware deletes files without you noticing it before it is too late.

A friend of mine lost some important data because of the ovh server container fire incident. Ovh had no backups.

Buyvm has 1TB for $5, but you need a GPS to connect to it, that is another $2. So $7 total for a small linux box with 1TB.

If you're into SCP/FTP/Rsync/SMB check out Hetzner Storage Servers. About 3 € for 1 TB, including 10 snapshots

Not sure about cheapest, but Wasabi is affordable considering no data transfer fees

I wanted to do my own self-hosted storage but for the cost and features I went with Dropbox. It's $10 a month if you prepay for the year otherwise it's $12 and you get two terabytes of storage. For that you get all the same things most self-hosted solutions will offer including 30 days of versioning/backups. Additionally it's pretty popular so most software has built in integration which is convenient but not something you need. Bottom line is doing your own storage can be cheap but adding off-site backups gets expensive and just going straight to off-site backups (cloud storage) is going to be close to the $10-$12 dollars you'll pay anyway but you have to do all the work.

I use either Discord or the unlisted feature of a random video/audio website depending on the circumstances.
