Same issue here. I just did reset several terabytes of backups about two months ago due this error. Now it appeared again. Yet, after updating to latest duplicati there was positive development. Running repair actually fixed the issue. So I didn’t need to reset the backup set(s).
That’s great advancement that repair works. Even better would be that it wouldn’t need the manual running of repair. Automatic error detection and recovery is what I’m always looking for, if possible.
- Thank you
