Hi, I did a restic backup (using rclone backend) of my external HDD that contains more than 3TB of data (documents, pictures, large ISOs, large videos, …) to pCloud. Overall, this backup took about a day and finished successfully, although there were some connection issues and I had to cancel and (re)start the backup at one point because the HDD was running very hot. The backup finished successfully. After doing a repo check I got the damaged pack files error and I don’t know how to resolve this.
