Aws Glacier
In the ever-expanding landscape of cloud services, efficient data management is a critical component for organizations seeking secure, scalable, and cost-effective solutions. Amazon Web Services (AWS) Glacier, a part of the AWS storage suite, stands out as a reliable cold storage service designed to address the unique needs of long-term data archiving and backup. In this blog, we'll delve into the world of AWS Glacier, exploring its key features, use cases, and best practices for optimal data preservation.
Understanding AWS Glacier
Amazon Glacier is a secure, durable, and extremely low-cost cloud storage service for data archiving and long-term backup.
Customers can reliably store large or small amounts of data for as little as $0.004 per gigabyte per month, a significant savings compared to on-premises solutions.
To keep costs low yet suitable for varying retrieval needs, Amazon Glacier provides three options for access to archives, from a few minutes to several hours.
Amazon Glacier offers three different retrieval options to fit your use case.
Expedited retrievals typically return data in 1-5 minutes, and are great for Active Archive use cases.
Standard retrievals typically complete between 3-5 hours and are suitable for less time-sensitive needs like backup data, media editing, or long-term analytics.
Bulk retrievals are Amazon Glacier’s lowest-cost retrieval option, which you can use to retrieve large amounts, even petabytes, of data inexpensively in a day.
