Download back-up .tgz always takes the latest that's created

[GuidoHub]

I have created several backups on my production enviroment. When I choose to download the backup tgz, never mind which you click it always downloads the latest created backup. I have checked folder "/var/backups" and all back-ups are there.

Preconditions

1. Magento 2.1.7
2. PHP 7.0.20

Steps to reproduce

1. Create several back-ups
2. Click on a backup (.tgz), different then the latest to download

Expected result

1. I would expect the backup I clicked.

Actual result

1. Always getting the latest back-up
