I'm testing Drive Snapshot and what got me really interested was this script: https://github.com/pcanterino/dsmonrot However, I've got a problem. I try to interrupt the script (close the PowerShell window while creating the backup) the backup script stops, it's normal. When I try to rerun the script, it closes itself and it can't do the full backup again, because the backup files still exist in my backup folder. It only works when I manually delete them. It doesn't replace the failed files with new ones. How to configure this script to delete unsuccessful full backup files and create the new one, of course in the same folder. This way I can be sure that backup is created every time I run it. The error occurred because it can't do the differential backup because of the wrong hash file and the backup file because I cancelled making the backup. What I want is that the script (if cancelled) should do the process again (delete wrong files and start the backup again)
