Quick Backup is designed to create a backup as quickly as possible, which is why it uses the backup job with the most recent restore point for the selected VM.
This approach allows Quick Backup to back up only the smallest amount of changed or new data, resulting in faster backup sessions compared to starting one of the older backup jobs.
Best practice is to write backups to the same location as your virtual machine initially, and then use a backup copy job to replicate the backup offsite. Are you using a different design?
