[HamWAN PSDR] Do we have any cloud / distributed storage experts?

We’re looking for recommendations on what to use, and how to set it up. As Bart mentioned, the critical aspects of this are N-way redundancy so that any given fragment of the network if it gets separated can still operate, and then graceful handling of re-syncing after the network rejoins.

I'm wondering if anyone in the group has knowledge to provide some design feedback in distributed storage systems.  Not from a "how to use it in AWS" perspective, but rather how to design them ground-up.
