Hi everyone,
I ran into a worrying issue with photo backup in the UGREEN NAS mobile app and wanted to check if anyone else has seen this.
Before deleting anything from my phone, the app showed that everything was backed up. I trusted that status, removed/reinstalled the app, and after setting it up again, it suddenly found 1,000+ additional photos that still needed to be backed up.
That makes me concerned that the app’s “backup complete” status may not be reliable, or that it is using some local app state/cache rather than fully verifying against the actual photo library and NAS contents.
A few questions:
- Has anyone else had the app say everything was backed up, only to later discover many photos were missed?
- Is there any reliable way to force a full rescan/recheck of the phone photo library?
- Does the app compare against existing NAS files, or does it only track what it has uploaded locally?
- Is there a safe workflow for confirming all photos are backed up before deleting them from the phone?
This feels pretty risky because the main purpose of photo backup is trust. If the app reports that everything is backed up when it is not, users could lose photos permanently.
Any advice or similar experiences would be appreciated.
