My automated monthly backups have been failing since March. I only just noticed when I tried to do a manual backup before updating my Unraid OS and the backup failed. Is anyone else having issues with backups? I have attached a log. 2025-08-05-appdata backup error log.txt Update: the culprit seems to be the Plex Cache folder. After looking at the Hints section of the original post at the beginning of this thread I was able to exclude the Cache folder and resolve the issue. Thank you!
