NAS
A NAS can provide local control and fast home access, but it still needs independent backup copies and a site-resilience plan.
Cloud
A cloud service can simplify offsite access, but recovery speed, recurring cost tolerance, and account recovery need consideration.
Hybrid
A local primary with an offsite component can combine fast access with separation from a home-site event.
Decision checklist
Measure data, define recovery expectations, identify privacy and control requirements, then create an independent-copy plan. Use the topology selector and Home Storage & Backup Planner.
