Scenario == backup everything from local devices + cloud accounts/storage (e.g., iCloud, Dropbox, etc) all back down into a locally owned NAS. Use case == customer can use whatever backup whenever on whatever device, and rely on this service to hoover it all up and sync it to a big local NAS so it's all there when needed (and optionally allows deleting various cloud sync accounts or restoring/syncing cloud accts from big local NAS if needed)
