Works unless local laws specifically block you doing that which they do for some classes of data in some countries.
Multi-cloud in the same country (if that exists in the country and is far enough apart) maybe.
Do cloud providers even share data center locations so you can assess the "far enough" bit yourself?
In this case, a local on-prem backup in your office-that-is-not-an-aws-datacenter would've worked and satisfy the law right?
(or an AWS Outpost thingy, assuming those things work even if the mothership is down)
I wonder what exactly these laws prohibit. Like, does it apply to a fully encrypted cold-copy on Amazon Glacier? If you don't store the encryption key outside of UAE, I'd say this isn't even the same data that gets transferred to the third party, it's just some random blob. But I have no idea if the authorities of that country would agree and if it's even actually enforced for that matter, or if it's one of those laws that actually cause problems only if you follow them.
