In case anyone ever comes here looking for an actual answer (since Updraft still hasn’t provided one) here’s my issue and the resolution I found:
- I have remote storage for one of my websites using Dropbox
- I consistently saw ghost files showing up in the list of backups on my site that I had already deleted from Dropbox. (ie, files from april and may that didn’t exist in my dropbox folder).
- I rescanned remote storage several times, disconnected Dropbox and readded it, nothing worked.
- I went in to attempt deleting the files one more time from updraft’s plugin on the site and noticed a checkbox in the “are you sure” pop up that said “Also delete from remote storage”. I’d always left that checked, but decided to UNcheck it this time.
- Voila! The files disappeared when I rescanned one more time.
- I was thinking maybe it was a weird glitch/remnant in updraft’s local files that they haven’t properly coded to delete correctly. This seems to be correct from the repro steps. Hope this helps someone!
