Since 1.8.* > Many schedule backup problems, Backup schedule does not stop even after deleted

After trying for a long time now, found many issues with scheduled backup (both remote panel backup and local home backup). Do look into it as it hasnt been working properly since many versions ago.

Another issue, where to check what (backup) cronjobs cyberpanel has? Had removed scheduled backup to be replaced by my own cronjob but cyberpanel continues to make triple backups everyday that cannot be restored.
