I have a bit of an odd question. I stored several hundred gigabytes of disk image files (100+ GB each) on Amazon Glacier several years ago, shortly after Amazon Glacier launched. I'm not a web or app developer and just uploaded the files using SAGU (Simple Amazon Glacier Uploader). Now I'd like to retrieve my files without spending a fortune. When I first uploaded the files to Amazon I had no understanding of Glacier's download pricing structure. Twice I accidentally racked up huge bills, which Amazon very, very graciously forgave.
What should I do next? Is there a way to cheaply move the data into something designed for more flexible downloading and then download it from there? As I said before, I'm not an AWS developer; but I am comfortable using a command line if I'm told what to do.
