Hello @komir2004 and welcome to the forum! I noticed from [Upload speed to Google Drive](https://forum.duplicati.com/t/upload-speed-to-google-drive/6054) that you might have a poor Internet connection. That might be related to this failure. My way of [reproducing](https://forum.duplicati.com/t/unexpected-difference-in-fileset-errors-2-0-3-9/4286/19?u=ts678) a similar failure involved a connection with a simulated failure. Especially if you have any added logs, they would be worth a look. Alternatively, just look at your job logs in Job --\> Show log --\> General (or other backup reports if you have any) for problems up to 2 versions back. Message reference to “version 1” means (I think) that the problem was discovered on the previous backup. The way to resolve it so that further backups can continue is simply to delete the version with the problem. [Here](https://forum.duplicati.com/t/mismatching-number-of-blocklist-hashes-detected-on-blockset/5545/5?u=ts678) are some directions, and because your message says “version 1”, the [–version](https://duplicati.readthedocs.io/en/latest/06-advanced-options/#version) to delete would be 1. Maybe after things are back to normal, we can look for clues about what led up the error, so it can be fixed. --- _[View the full topic](https://forum.duplicati.com/t/error-unexpected-difference-in-fileset-version/6104)._
