As always we are adding features to make it easier for our customers to use the functionality to offer the most compelling Amazon S3 , CloudFront , IAM and Glacier client on Windows platform.
Amazon Glacier, a secure, reliable and extremely low cost storage service designed for data archiving and backup. In order to keep costs low, Amazon Glacier is optimized for data that is infrequently accessed and for which retrieval times of several hours are suitable. With Amazon Glacier, you can reliably store large or small amounts of data for as little as $0.01 per gigabyte per month.
CloudBerry S3 Explorer has supported Glacier for quite some time now.  We introduced the Glacier support in September, followed by supporting encryption and compression and finally Amazon S3 to Glacier archiving.
Amazon Glacier is designed for very infrequent restores and restore costs may be substantial. And in fact it is very confusing. Check out the following article from Amazon FAQ.

The data restore is charged based on the pick usage during the given month. In other words if you have to restore 100GB and you restore them in 1 hours you will pay one amount. But if you restore 1GB for the next 100 hours you will pay 100 times less.

In the latest release of CloudBerry Explorer PRO v 3.8 we are introducing the Smart Retrieval functionality, that allows you to manage data restore budget in an intelligent way.
When you run a copy for Glacier it will pop up a dialog asking you to specify your peak retrieval rate in MB.  It will also allow you to allocate data retrieval to run for a number of hours to stay within a selected budget. This way you can significantly reduced your retrieval costs.

After you set it up, the restore will run in the background retrieving the portions of data every hour. Note, you can also access this dialog from Tools | Options menu
You can monitor the restore progress on the bottom panel.
