Backup to aws s3 pricing8/7/2023 This differentiation is important when you look at the costs of the services. As such they are still managed as objects within S3buckets, instead of Archives within Vaults, which is the Glacier terminology. 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.
