/u/Madman200 have you tried using the 1TB monthly free egress that cloudfront offers to handle downloading the exports?

I've been experimenting with using Deep Archive myself, and I suspect that if I:

1. Restore a Deep Archive object
2. Copy that object to a new S3 bucket
3. Set up a cloudfront distribution with an S3 origin
4. Download the object through the Cloudfront distribution

the download would consume the "Always Free" 1TB bandwidth instead of being considered normal data egress.

I'm pretty sure 1TB out to a single IP address is an unintentional use, but Cloudfront + S3 looks like a normal CDN-type use to me.

I'm just waiting for a restore to complete before trying this and seeing what shows up on my AWS bill.
