How does cloud storage work?
Quick answer
Cloud storage keeps your files on powerful computers (servers) in remote data centers instead of only on your device. When you save a photo to the cloud, it uploads over the internet to those servers, which copy it across machines so you can reach it from any device, anytime.
Step by step
- Your files live on servers in remote data centers.
- They upload and download over the internet.
- Copies are kept on multiple machines for safety.
- You can access them from any signed-in device.
