Backups marked incomplete, but seem to be full backups, while using vultr VPS with WHM Cpanel destination Amazon S3. How do I resolve this?

OK! So I found my issue. Exporting of a mySQL database was failing during the backup. I found this by reviewing the cpanel log files found in /usr/local/cpanel/logs/cpbackup
