For about 2 weeks, all my backups are failing with this code, "Failed to open file". The directory being saved to is about 660GB, and the external drive it's on checks fine. Reboot doesn't solve the issue.
Is there any way to find out what file won't open? Is this referring to a file being backed up, or the backup file?
Would my next step be to make a new backup task and delete the old one?
