In Amazon calculator for Glacier there's a section of data transfer out. When does this fee applies? I understand that data transfer out relating to EC2 means the bandwidth of data that people will download from my server on EC2. But what does it have to do with Glacier??
For example, if I download my backup file via FastGlacier (Windows Client for Amazon Glacier) to my personal PC will I be charged for the data transfer fees in addition to data retrieval fees? If not, in what Glacier related scenario does a data transfer out fee apply?
I tried to contact Amazon support but couldn't understand much from their answers.
