Backup restoration and migration

So, I had to go nuclear and I’ve ended up with only a singular cloud backup of what was a Synology DS 412+.

The backup itself is through the Synology Amazon Glacier app.

I’m looking to ultimately move the data away from both Amazon and Synology.

My question then falls into two parts:

1. Am I able to extract said archive from Amazon without using the Synology app?

2. If the above is not possible, am I able to run the Synology os on hardware not from Synology itself?

I do understand the data extraction can end up being pricy even at a mere 12TB. I’m okay with that. That’s the price we’ve accepted for making it easier to move across the world.
