Thanks for answering this post! The issue has been resolved now, and since it’s a while later, I’m fuzzy on the details. Basically, it turned out I had a corrupted hard drive. I had to reformat the drive and restart my backups from scratch.
I did find the filelist under C:\Program Files\UrBackup\urbackup\data, and while I’m guessing, it probably contains info on which files/folders I’ve chosen to backup. Probably someone else could answer that definitively.
Figured I’d write all this up in case this is somehow useful when someone is searching. I know I was vague in the OP but it was mostly because I only was concerned with what this filelist was.
