A photo backup workflow succeeds when it can restore the right image after a mistake, device loss, or interrupted transfer. Upload success and synchronization alone do not answer that question.
Choose what must be recovered: original files, edited versions, albums, captions, or metadata. Then define retention, deletion, and recovery rules. A system that immediately propagates every deletion may be convenient for synchronization, but it needs a separate recovery mechanism to protect against accidental loss.
Record which assets are eligible and what permission allows access. Treat unavailable cloud-backed or device-only items as explicit states.
Persist progress, detect duplicates with an appropriate identity scheme, and resume safely after interruption. Do not equate a queued upload with a protected original.
Separate current library state from retained backup versions. Define retention windows, deletion authorization, and what a user can recover.
Periodically restore representative photos and associated information. Check that the recovered files open and that the user can understand what was restored.
| Scope | State whether you preserve originals, edits, albums, and metadata. |
|---|---|
| Connectivity | Handle interrupted and metered connections without duplicate transfers. |
| Retention | Document how deletion affects active data and recoverable copies. |
| Recovery | Set recovery goals that can be tested with actual restores. |

It can be one component, but recovery depends on retention and deletion behavior. Check whether you can recover from the specific mistakes your users are likely to make.
It can support backing up selected items that your app can access. It does not automatically provide ongoing library-wide access or permission to process future photos.
Use concrete states such as waiting for access, uploading, verified, and needs attention. Explain which assets and versions each status covers.
Design photo backup around recoverability: independent retention, verified originals, resumable uploads, and tested restores. This guide explains how to separate device changes from archive policy and make backup status understandable to the people trusting your app.
