S3 objects that have been moved to Glacier storage using S3 Lifecycle policies can only be accessed (or shall I say restored) using the S3 API endpoints. Amazon GlacierĪt this stage, we need to highlight the difference between the ‘pure’ Amazon Glacier service and the Glacier storage class within Amazon S3. This is reflected in the pricing, where extensive restores come at an additional cost and the restore of objects require lead times of up to 5 hours. Amazon Glacier is pretty much designed as a write once and retrieves never (or rather rarely) service. The cost per Terabyte of storage and month is again only a fraction of the cost of S3. After a set period of time, you can either have your objects automatically delete or archived off to Amazon Glacier.Īmazon Glacier is marketed by AWS as “extremely low-cost storage”. Lifecycle rules within S3 allow you to manage the life cycle of the objects stored on S3. Therefore you don’t need to second-guess and pre-allocate disk space. You also only pay for the amount of storage you actually use. For one, Amazon can provide a highly durable storage service for the fraction of the cost of block storage. The abstraction away from the lower layers of storage and the separation of data from its metadata comes with a number of benefits. Unlike Amazon’s Elastic Block Store (EBS) or the local file system of your traditional PC, where data is managed in a directory hierarchy, Amazon S3 treats data as individual objects. So, what about Amazon S3 vs Amazon Glacier? Thanks to Amazon’s Simple Storage Service (S3) and its younger sibling, Amazon Glacier, you have the right services at hand to establish a cost-effective, yet practical backup solution. This can only be mitigated with an effective backup strategy. While you may have designed a highly resilient and durable solution, this won’t necessarily protect you from administrative mishaps, data corruption, or malicious attacks against your system. When you set out to design your first AWS (Amazon Web Services) hosted application, you will need to consider the possibility of data loss.

Feel free to check out MSP360 Backup 6.0 and share your feedback in the comment section below.Amazon S3 vs Amazon Glacier: which AWS storage tool should you use? MSP360 Backup 6.0 significantly improves S3 backup by introducing direct upload to Glacier and support for Amazon's latest Intelligent-tier storage class which automatically determines if the data should be stored under the infrequent storage tier.
Once you've finished configuring the backup plan, execute it and your newly backed up data will be stored under the Glacier storage class. To back up data directly to Glacier, select the Glacier storage class on the Compression and Encryption step of the Backup Wizard. Direct Upload to Glacier in MSP360 Backup 6.0Īnother S3-related improvement is the ability to back up data directly to the Glacier storage class instead of the previous approach where data would first be uploaded to S3 and then moved to Glacier. Once you've finished configuring the backup plan, execute it and your newly backed up data will be stored under the Intelligent-Tiering storage class. To do that, select the Intelligent-Tiering storage class on the Compression and Encryption step of the Backup Wizard. MSP360 Backup 6.0 provides the ability to back up data directly to the Intelligent-Tiering storage class.
Because of this, Standard-IA is still a better choice for infrequently-accessed data if you want to optimize storage costs. However, please note that Amazon charges you a small monitoring and automation fee for Intelligent-Tiering. This approach is convenient if at the time of backup you don't know if the data will be frequently accessed. For example, if you store some data under Intelligent-Tiering and you don't access that data within 30 days, Amazon will automatically move it from the default frequent access tier to the infrequent access tier. It's primarily aimed at customers who want to automatically optimize storage costs when data access patterns change. Support for S3 Intelligent-Tiering in MSP360 Backup 6.0Īmazon has recently announced its latest S3 storage class - S3 Intelligent-Tiering. MSP360 Backup 6.0 brings two notable improvements to S3 backup - direct upload to Glacier and support for Amazon's latest Intelligent storage tier.
