I realized that Cloud Storage is maybe too flexible hence the cost. What if I only needed an off-site backup and I don't expect to ever need to restore from it?

• Acronis - $300 for 10 TB, unsure if this includes external HDs.
• Backblaze - $100 per year for all data on your computer and connected external drives
• Carbonite - $80 for one computer and one external HD.

Doesn't seem to be a lot of choices. Backblaze and Carbonite have been around forever. I think I've heard of Acronis.

Backblaze seems to be the best choice here and at that price I should research more and consider it.
