I finally defeated the final boss of my backup migration to Proton Drive.
For months, I have been trying to sync my 500GB media library (around 80k files) to Proton Drive. Every single time, the sync crashed with the exact same error: "1 item failed to backup." The only clue I had was a blurry thumbnail named "Asset 1". No date, no metadata, no search tags.
I was so frustrated that I even asked Proton support to completely wipe my encrypted volume so I could start from scratch. The result was exactly the same.
Finding this file became a manual protocol. I spent months periodically scanning through thousands of files just looking for a visual match to that tiny thumbnail. I finally found it today. It was an old scan from 2017. It was completely frozen - uneditable, unindexed, and gave an error when I tried to export it from my phone.
I managed to track it down via macOS. When I forced an export there, the truth came out: it was not an image at all. It was a .pdf file somehow saved into the photo gallery, and it was silently breaking the entire upload queue.
Removing it fixed everything. The sync is finally 100% complete. The relief of finally closing this mental background process is unmatched.
