Amazon Cloud Drive and Zoolz Cold Storage: have experience with either or both?

[conceptualclarity]

Both are on sale now.

Any information, such as ease of usage, is welcome.

Zoolz is from the same company as Genie Timeline.

Can you keep system images on these services?

Any alternative suggestions for cloud storage and/or software for managing cloud storage are welcome.

Amazon Cloud Drive is no longer on sale. Zoolz is at a big bargain for at least a few more hours.
