Borg: file changed while we backed it up

Has anyone noticed that borg backups fail on changed files? Which causes it to be not stored in the DB.

From the cron.log:

web/wp-content/wflogs/config-transient.php: file changed while we backed it up
ERROR - Backup of web files for domain example.com using path /var/www/clients/client1/web2 failed.

I know that there is a risk for corruption in such cases, however the file in the backup is actually OK in this case.

Not showing the backup at all to the user is not ideal. Only admins can see this log. Maybe we could add a field that shown the status and can represent this status as a warning.

One solution for this particular site might be to add this file to the exclude list.
