Are you using OpenDedupe to replicate to cloud?
This will ensure that deduplicated data is sent to cloud and only changed blocks for subsequent backups (full or incremental).
You need to have Dedupe license (Included in Bronze, Silver and Gold licenses).
About Verify - the recommendation is to turn verify of for cloud backups (Default in recent versions) because cloud vendors charge for read operations.

What do you lose by not performing a Verify?
IMHO - I have learned to trust that successful status really means that the operation was successful.
My view is that regular restore tests is the best way to know - obviously at a cost when cloud is involved, but less than Verify after each replication.
It might also be worth checking out other cloud vendors that don't charge for egress (eg you don't pay to access or download your data once its there), such as Wasabi (https://wasabi.com/cloud-storage-pricing/) however I'm sure there are others out there too. This would mean no extra cost for running a verify.
Though appreciate choice of cloud provider may be regulated by your company policy.
