The backup process completed, but 2 errors occurred.

Hello,

We started having trouble with cPanel backups on multiple servers. Because of this error, the backup directories don't get pruned (although I know that can be controlled, but I don't want to change it, as that might leave only corrupted backups for some users). Looking at the logs, I see the following:

Code:

This error now appears on multiple servers. Is there something that I should check for the specific users that are getting this error during the backup process?

Thank you.
