backup - Restore disk image while in rescue mode

I have taken a backup from my Linux disk using dd command and I've uploaded it to a website.

Now there is a kernel panic in my VPS and I open the rescue mode and I want to download and restore that backup image.

My question: Since my kernel is not booting and The I can't mount the disk that I want to restore, where I can download the disk image to restore it?
(The disk image is about 5 GB)

Regards,
