Automatic Data Backup On Amazon S3
Amazon S3 provides a highly durable storage infrastructure designed for mission-critical and primary data storage. Amazon S3 redundantly stores data in multiple facilities and on multiple devices within each facility. To increase durability, Amazon S3 synchronously stores your data across multiple facilities before confirming that the data has been successfully stored. In addition, Amazon S3 calculates checksums on all network traffic to detect corruption of data packets when storing or retrieving data. Unlike traditional systems, which can require laborious data verification and manual repair, Amazon S3 performs regular, systematic data integrity checks and is built to be automatically self-healing.
Amazon S3 provides durable infrastructure to store important data and is designed for durability of 99.999999999% of objects. Your data is redundantly stored across multiple facilities and multiple devices in each facility.
Amazon S3 is designed for 99.99% availability of objects over a given year. Amazon S3 is also backed by the Amazon S3 Service Level Agreement, ensuring that you can rely on it when you need it. And you can choose an AWS region to optimize for latency, minimize costs, or address regulatory requirements.
Amazon S3 supports data transfer over SSL and automatic encryption of your data once it is uploaded. You can also configure bucket policies to manage object permissions and control access to your data using AWS Identity and Access Management (IAM).
Amazon S3 supports multi-part uploads to help maximize network throughput and resiliency, and lets you choose the AWS region to store your data close to the end user and minimize network latency. And Amazon S3 is integrated with Amazon CloudFront, a content delivery web service that distributes content to end users with low latency, high data transfer speeds, and no minimum usage commitments.
With Amazon S3, you can store as much data as you want and access it when you need it. You can stop guessing your future storage needs and scale up and down as required, dramatically increasing business agility.
Amazon S3’s highly durable, secure, global infrastructure offers a robust disaster recovery solution designed to provide superior data protection. Whether you’re looking for disaster recovery in the cloud or from your corporate data center to Amazon S3, AWS has the right solution for you.

AWS is located in 11 geographical “regions”: US East (Northern Virginia), where the majority of AWS servers are based, US West (northern California), US West (Oregon), Brazil (São Paulo), Europe (Ireland and Germany), Southeast Asia (Singapore), East Asia (Tokyo and Beijing) and Australia (Sydney). There is also a “GovCloud”, based in the Northwestern United States, provided for U.S. government customers, complementing existing government agencies already using the US East Region. Each Region is wholly contained within a single country and all of its data and services stay within the designated Region.
Each Region has multiple “Availability Zones”, which are distinct data centers providing AWS services. Availability Zones are isolated from each other to prevent outages from spreading between Zones. Several services operate across Availability Zones (e.g., S3, DynamoDB) while others can be configured to replicate across Zones to spread demand and avoid downtime from failures. As of December 2014, Amazon Web Services operated 1.4 Million servers across 28 availability zones.
