CloudBerry Explorer vs Fast Glacier

Amazon Glacier is used to store infrequently accessed data such as backups. It can be managed through a web console similar to Amazon S3, but with limited functionality. That’s why you definitely need a file manager to successfully handle Amazon glacier vaults: store and retrieve the data as easy and conveniently as possible. Below we will compare the main features and usability of CloudBerry Explorer and FastGlacier file managers for Amazon Glacier.

User Experience

A powerful yet transparent interface is what you expect to see in the first place when deciding to store data in Amazon Glacier. CloudBerry Explorer provides a classic Total-Commander-style 2-pane interface to navigate local files alongside objects in the vault. The panes are independent so you can transfer data between different sources, both local and on the cloud, including Amazon S3 and other S3 compatible storages. With FastGlacier, however, you cannot work with local drives or Amazon S3 buckets directly. You should install another Amazon S3 file manager and use it separately. In order to update local files you also have to switch constantly between the FastGlacier app and Windows Explorer.

Uploading and Retrieving data from Amazon Glacier

CloudBerry Explorer provides its users with unlimited simultaneous uploads and downloads both in the free and pro versions, while FastGlacier limits the amount of concurrent threads to two in the free version.

Both applications support drag-and-drop when it comes down to uploading the data to the cloud. CloudBerry Explorer comes with a Windows PowerShell snap-in to help automate and schedule recurring tasks like backups and cleanups. If automated and secure data backup and archiving is what you are looking for, check out our CloudBerry Backup. It has a set of features designed specifically for automated secure backups to the cloud.

CloudBerry Explorer and FastGlacier both help to decrease data retrieval costs. Amazon Glacier fee calculations depend on “retrieval peaks” — the highest amount of downloaded data per hour. The Smart Restore feature limits the restoration speed and allows to control bills. Learn more about Smart Restore in our blog post.


Server-side encryption is available in both file managers. Client-side encryption comes in FastGlacier freeware and is not supported in the CloudBerry Explorer free version, but is available in the Pro edition.

FastGlacier is able to create external vaults for users using limited IAM Accounts. It helps to grant access to the vault for users with different Amazon accounts, whereas CloudBerry Explorer supports permissions management via ACL settings, IAM roles or vault policies.

CloudBerry Explorer comes with Policy Designer designed to ease the access configuration process. At the same time FastGlacier customers must write all scripts by themselves. CloudBerry Explorer has also a feature called Security Assessment Report that enables you to see how many public vaults you have.
