Let's assume that with Glacier you can retrieve your 1000 GB in 4 hours instead of 3 days. You will be surprised by a retrieval fee of 1000 / 4 * 720 * 0.01 = $1,800. If you want to get your 1000 GB for free, you'd have to request no more than 69 MB per hour. It will take you about 20 months to get your data! With Glacier, limit retrievals to less than 5% per month / 30 days / 24 hours = 0.007% of total data stored per hour to avoid these ugly surprises.
