How to reduce the EBS snapshots storage cost

Here are some ways to reduce the storage costs for Amazon EBS snapshots:

Leverage the EBS Snapshots Archive storage tier:
  • The EBS Snapshots Archive tier is much cheaper, costing about $0.0125 per GB-month compared to the standard tier's $0.05 per GB-month. 
  • It's ideal for archiving infrequently accessed snapshots like monthly, quarterly, or yearly backups. 
  • Retrieving data from the archive tier costs an additional $0.03 per GB.
Optimize snapshot retention:
  • Regularly review and delete unnecessary snapshots, especially older ones not part of the current volume lineage. 
  • Consolidate multiple incremental snapshots into a single full snapshot to reduce storage footprint.
Disable and archive snapshots for unused AMIs:
  • Disable unused Amazon Machine Images (AMIs) to prevent new instances from launching. 
  • Archive their snapshots to the lower-cost EBS Snapshots Archive tier to maintain compliance and reduce storage costs for rarely accessed snapshots.

Where the EBS snapshot stores and snapshot charges

Your Amazon EBS snapshots are stored in Amazon S3. When you create an EBS snapshot, it is automatically stored in the S3 bucket associated with your AWS account. The specific location where the snapshot is stored is not directly accessible to you, as AWS manages the underlying storage infrastructure. Here are a few key points about where your EBS snapshots are saved: EBS snapshots are stored in the AWS region where you created them. Each AWS region has its own set of S3 buckets where the snapshots are stored. The snapshots are stored in a secure, durable, and highly available manner within the S3 infrastructure. AWS manages the storage and replication of your snapshots to ensure data durability and availability. You can view the list of your EBS snapshots in the AWS Management Console, but you cannot directly access the S3 bucket or location where they are stored. AWS manages the storage and retrieval of your snapshots on your behalf. If you need to restore an EBS volume from a snapsho...

Difference between full snapshots and incremental snapshots

The differences between full snapshots and incremental snapshots in Amazon EBS are: Snapshot Type: Incremental snapshots: These snapshots only store the changed data blocks since the last snapshot, making them more efficient and cost-effective for frequent backups. Full snapshots: When you archive an incremental snapshot, it is converted to a full snapshot that includes all the blocks written to the volume at the time the snapshot was created. Incremental snapshots store only changed data blocks since the last snapshot, making them efficient and cost-effective for frequent backups.  When the increamental snapshot is archived, they are converted to full snapshots , that including all blocks written to the volume at the time of snapshot creation. Storage Tier: Incremental snapshots are stored in the Standard tier by default. Full snapshots are stored in the Archive tier after being converted from an incremental snapshot. Retrieval and Cost: Incremental snapshots in the Standard tie...

Snapshot storage tier types and cost difference

The key points on the different storage tiers and cost differences for EBS snapshots: Standard Tier: This is the default storage tier for EBS snapshots. Snapshots stored in the standard tier are incremental, meaning only the changed data blocks are stored. The pricing for the standard tier varies by AWS region, but is typically around $0.05 per GB-month. Archive Tier: The archive tier is a lower-cost storage option for rarely accessed snapshots. When you archive a snapshot, it is converted to a full snapshot (not incremental) and moved to the archive tier. The pricing for the archive tier is significantly lower, typically around $0.0125 per GB-month. However, there is an additional charge for retrieving data from the archive tier, around $0.03 per GB. Cost Savings: Archiving infrequently accessed snapshots to the lower-cost archive tier can result in significant cost savings, up to 75% compared to the standard tier. The savings are more substantial at larger scales, where there are mul...

Pros and cons of On-Demand, Reserved, Spot and Saving Plans EC2 instances

The pros and cons of the on-demand pricing model for EC2 instances are: Pros: Flexibility: On-demand instances allow you to scale your compute resources up or down as needed, without any long-term commitments. No upfront costs: With on-demand, you only pay for the compute capacity you use, without any upfront payments or long-term contracts. Suitable for unpredictable workloads: On-demand is well-suited for applications with short-term, spiky, or unpredictable workloads that cannot be interrupted. Ideal for development and testing: On-demand instances are a good choice for workloads like pre-production environments, experiments, and proofs of concept. Cons: Higher costs for long-term, steady-state workloads: Compared to other pricing models like Reserved Instances or Savings Plans, on-demand instances can be more expensive for long-term, steady-state workloads. No long-term discounts: On-demand instances do not offer any long-term discounts or commitments, unlike Reserved Instances...

Difference b/w General-purpose and a Directory bucket in Amazon S3

  The key differences between a general-purpose S3 bucket and a directory bucket in Amazon S3 are: Purpose: General purpose S3 buckets are the standard type of S3 buckets used for storing objects. Directory buckets are a specialized type of S3 bucket designed for use with the AWS Application Discovery Service. Naming Conventions: General purpose S3 bucket names must be unique across all AWS accounts and regions. Directory bucket names must follow a specific naming convention:  <name>--azid--x-s3 , where  <name>  is a unique identifier. Inactive State: Directory buckets that have no request activity for at least 90 days can transition to an inactive state, where they become temporarily inaccessible for reads and writes. General purpose S3 buckets do not have this inactive state behaviour. Access and Permissions: Access to directory buckets is typically restricted to users with permissions to the AWS Application Discovery Service and Migration Hub. General ...

How the Amazon S3 data transfer charges work

Here's how the Amazon S3 charges work: Storage Charges: You are charged based on the amount of data stored in your S3 buckets, measured in gigabytes (GB) per month. The storage charges vary depending on the S3 storage class you use (e.g., S3 Standard, S3 Glacier, S3 Intelligent-Tiering). Request Charges: You are charged for the number and type of requests made to your S3 buckets, such as GET, PUT, COPY, POST, LIST, and DELETE requests. The request charges vary based on the request type and the number of requests made. Data Transfer Charges: You are charged for the amount of data transferred out of the S3 region, measured in gigabytes (GB). Data transferred between S3 buckets or from S3 to other AWS services within the same AWS Region is free. Management and Replication Charges: You may be charged for enabling certain S3 management features, such as S3 Inventory, S3 Analytics, and S3 Object Tagging. If you enable cross-region replication, you may incur additional charges for the  re...
