Backup and resume

Send to Computer copies photos you explicitly select. Backup is a separate workflow that checks original files against your paired Photo PC and transfers what is missing. Both require Pro or active three-day access.

The backup flow

Section titled “The backup flow”
  1. Connect and verify the computer

    Keep Photo PC open and wait until LogicPhoto confirms the direct connection.

  2. Choose the backup scope

    Tap Back up all for the whole library, or Select photos to choose specific items.

  3. Let Photo PC check existing originals

    It verifies what is already stored and transfers missing files. Counts may differ while work is underway.

  4. Wait for completion

    Keep the computer online. If iOS pauses background work, return to LogicPhoto and use Continue.

  5. Clear the iPhone copy only after backup succeeds

    Deleting a local Apple Photos item does not delete its verified PC copy. To browse the PC library from iPhone, the computer must be online and directly reachable.

Start or update a backup

Section titled “Start or update a backup”
  1. Connect a computer and keep Photo PC open.
  2. Open the Backup task from the task panel on iPhone.
  3. Compare iPhone items with Verified originals. These are different measures and do not have to match one-to-one while work is underway.
  4. Choose Back up all, or Select photos if you need a smaller transfer. If the overview offers Update backup, it opens the same backup workflow.

The transfer should verify an existing original before sending bytes again. The displayed item count is not a promise that every file has been uploaded.

Pause, resume and background limits

Section titled “Pause, resume and background limits”

Use Pause and Continue in the Backup panel. A continued task can spend time checking a saved checkpoint before the visible count moves again; it should not discard verified work solely because the screen reopened. Keep the computer online. iOS may delay background execution, so return to LogicPhoto to inspect progress if a task appears still.

If progress stops with an error, check the PC connection first. Do not repeatedly start a new full backup while the existing task still offers Continue. If the app cannot continue, use Support with the displayed error and app version; do not send private photo files unless you choose to.
