Amazon Glacier started a revolution and changed the game. Since then, data backups and archiving have never been the same. You pay nothing upfront, a meager fee for the storage. You can scale your usage up or down as needed while Amazon Web Services does all the heavy operational lifting necessary for data preservation. Today, Amazon Glacier is recognized as a top-tier, reliable, and durable storage choice.

Additionally, data preservation is frequently too expensive. To begin with, businesses must spend a sizable up-front cost for their archiving system. Keep in mind that recurring costs for operating expenses like power, buildings, employees, and maintenance are not included. Second, enterprises understandably over-provision to guarantee they have enough space for data redundancy and unplanned growth as they must estimate their capacity demands. These circumstances result in a low capacity utilization rate.

Amazon Glacier: What is it?

A cheap storage option, Amazon Glacier provides secure, long-term storage for data backup and preservation. It is designed to be cost-effective for data that is only sometimes accessed and for which retrieval times of several hours are acceptable. Customers may confidently store large or small quantities of data with Amazon Glacier. In addition to offering complete security and compliance features that may assist fulfill even the most demanding regulatory standards, it is designed to achieve a durability of 99.999999999%.

Customers may store data for as little as $1 per terabyte per month, which is a significant cost saving compared to on-premises options. To keep costs down while satisfying a range of retrieval needs, Amazon Glacier offers three access options for archives, spanning from a few minutes to several hours, while S3 Glacier Deep Archive offers two access options, ranging from 12 to 48 hours.

Make sure you are familiar with the following terms before continuing. AWS Glacier Terminology:

1. Records

Data is kept in Amazon S3 Glacier’s “archive” section. Photographs, movies, and documents are just a few of the content types that may be stored in an archive. You can submit a single archive made up of a single file or a single archive made up of many files combined into a TAR or ZIP file.

Objects in S3 and Archives in AWS Glacier are interchangeable. As much as 40 terabytes may be contained in one repository.
Data and archives may be kept in your account indefinitely. The archive’s content is also immutable, which means that once it is formed, it cannot be changed. Each archive is also assigned a particular archive ID at the creation time.

2. Safes

Virtual data storage containers are called vaults. Vaults in AWS Glacier are comparable to buckets in S3.

The AWS Management Console displays a list of your vaults, and the AWS SDKs may be used to create, remove, lock, display vault information, retrieve inventory, tag vaults for filtering, and set up vault alarms.

Additionally, you may implement access policies to allow or disallow specific user behaviors for each vault. Also, region-specific is vaulted.

AWS Glacier’s salient characteristics are:

1. Data Recovery

Depending on your access time and cost requirements, your archives in Amazon S3 Glacier may be retrieved via Expedited, Standard, or Bulk retrievals. Expedited retrievals are commonly available in 1–5 minutes; however, standard retrievals typically take 3-5 hours.

S3 Glacier Select on Amazon

Amazon S3 Glacier Select enables queries to run directly on the stored data without requiring the acquisition of the whole archive. You may make financial savings and discover new information from your archived data using S3 Glacier Select.

3. Vault Lock

You may easily define and implement compliance limitations on specific S3 Glacier vaults using the lockable policy feature of Amazon S3 Glacier Vault Lock. In a Vault Lock policy, you can impose limitations such as “Write Once Read Many” (WORM) and lock the policy against future updates. Once locked, the policy is unchangeable, and Amazon S3 Glacier will implement the necessary safeguards to support your compliance objectives.

4. Access management

You can securely track who has access to AWS and your Amazon S3 Glacier data with the aid of AWS Identity and Access Management (IAM) by Amazon S3 Glacier.

5. Tag assistance

Tags are labels you design and attach to your vaults, and utilizing tags gives activities like AWS cost reporting new filtering features. You may tag your S3 Glacier vaults with Amazon S3 Glacier to simplify resource and expense management.

6. Audit records

Audit logging with Amazon S3 Glacier is made possible by AWS CloudTrail, which records API calls to Amazon S3 Glacier for your account and sends these log files to you. Looking at these log files, you may learn more about what’s happening with your Amazon assets.
