Amazon S3 provides a highly durable storage infrastructure designed for mission-critical and primary data storage. Objects are redundantly stored on multiple devices across multiple facilities in an Amazon S3 region. To help better ensure data durability, Amazon S3 PUT and PUT Object copy operations synchronously store your data across multiple facilities before returning SUCCESS. Once the objects are stored, Amazon S3 maintains their durability by quickly detecting and repairing any lost redundancy.
