In S3 What Does RRS Stand For?
Reduced Redundancy Storage (RRS) is a storage option in Amazon Simple Storage Service (S3) that enables customers to store noncritical, reproducible data at lower levels of redundancy than Amazon S3’s standard storage. Let’s deep dive on what is S3 RRS.
What is S3 RRS?
RRS provides a cost-effective redundancy level for data that can be reproduced, such as thumbnails, transcoded media, or processed data. Storing data in RRS can lower your storage costs by around 20-30% compared to S3 Standard storage.
When you upload an object to Amazon S3, it automatically stores it across multiple facilities and multiple devices in each facility. This provides high durability by ensuring that your data survives individual device failures as well as facility failures.
Amazon S3 Standard storage offers 99.999999999% durability and 99.99% availability, meaning your data is highly protected against loss.
RRS, in contrast, stores objects on fewer physical facilities than S3 Standard storage. It provides 99.99% durability and 99.99% availability. The slightly lower durability means that RRS provides a level of protection against data loss equivalent to reproducing the data within a year.
What Is The Durability Of S3 RRS?
The durability of Amazon S3 Reduced Redundancy Storage (RRS) is 99.99% compared to the 99.999999999% durability offered by S3 Standard storage.
This means:
- RRS provides 99.99% durability over a given year.
- The risk of irrecoverable data loss is slightly higher than with S3 Standard.
- RRS redundantly stores objects across multiple facilities and multiple devices, but with fewer copies than S3 Standard.
- The 99.99% durability equates to potentially losing 1 object for every 10,000 objects stored over a year.
- For S3 Standard the risk is extremely low – just 1 potential loss for every 100 billion objects over a year.
Key Facts About RRS
- RRS saves you 20-30% on storage costs compared to S3 Standard.
- Durability is 99.99% compared to 99.999999999% for S3 Standard.
- Availability remains excellent at 99.99% (same as S3 Standard).
- Data is stored redundantly across multiple facilities and devices, just with fewer copies.
- Ideal for reproducible data like thumbnails, transcoded media, and cache files.
- Not recommended for critical data or one-of-a-kind objects.
Use Cases for RRS
Some examples of using RRS for cost savings:
- Store thumbnail images, which can be reproduced from the original if lost.
- Cache heavily accessed but reproducible data like application logs.
- Store transcoded media files that can be re-transcoded if needed.
- Back up minimally processed dataset copies for disaster recovery.
The slightly higher risk of data loss with RRS may be acceptable for these use cases since the data can be recreated. The cost savings are substantial for larger volumes of data.
Recommendations
For mission-critical data, unique data, or primary production data, S3 Standard provides the highest level of durability. The extremely low risk of irrecoverable data loss makes it suitable for any application where data loss is unacceptable.
A hybrid approach is to use RRS for secondary copies of data while storing the primary copy in S3 Standard. This takes advantage of the cost savings from RRS while maintaining high durability for the primary data.
Conclusion
In this article we learnt about In S3 What Does RRS Stand For and What is S3 RRS along with its key facts.
In summary, RRS allows you to trade a small amount of durability for reduced redundancy and lower costs. It works best for reproducible data where a low risk of data loss is acceptable. Evaluate the tradeoffs and use cases closely before storing mission-critical or primary data in RRS.
