You almost certainly should not have 10PB of data. Not just is it extremely expensive, it is unlikely that millions of people have each allowed you to take gigabytes of their data. You are sitting on a huge violation of CCPA, GDPR, and other privacy laws, as well as copyright issues.

As a startup you do not have the legal and technical capabilities to manage this data so you should not have it.
