Release: AWS SDK for Java 1.0.4

Reduced Redundancy Storage (RRS) is a new storage option within Amazon S3 that enables customers to reduce their costs by storing non-critical, reproducible data at lower levels of redundancy than Amazon S3’s standard storage. It provides a cost-effective, highly available solution for distributing or sharing content that is durably stored elsewhere, or for storing thumbnails, transcoded media, or other processed data that can be easily reproduced. Amazon S3’s standard and reduced redundancy options both store data in multiple facilities and on multiple devices, but with RRS, data is replicated fewer times, so the cost is less. Amazon S3 standard storage is designed to provide 99.999999999% durability and to sustain the concurrent loss of data in two facilities, while RRS is designed to provide 99.99% durability and to sustain the loss of data in a single facility. Both the standard and RRS storage options are designed to be highly available, and both are backed by Amazon S3’s Service Level Agreement.

To upload a new object to Amazon S3 in the new reduced redundancy storage class:

PutObjectRequest request = new PutObjectRequest(myBucketName, myKey, myFile)
    .withStorageClass(StorageClass.ReducedRedundancy));
s3.putObject(request);

s3.changeObjectStorageClass(myBucketName, myKey, StorageClass.ReducedRedundancy);
