Is there a cloud-based archival storage?

Good time of day.

The question is as follows: the company is required to store archive data, at present about 20 TB with rare access to once a month or two folded, every few months something got (not full files). For big uncle, the solution is obvious - a tape library or two just fit perfectly into this scenario.

I would like to hear, are there any options for small companies, something like rental libraries by type of clouds or the like? Well, besides the obvious, like to get some more traffic.
