How do I use Amazon's new RRS for S3?

Question

Reduced Redundancy Storage (RRS) is a new service from Amazon that is a bit cheaper than S3 because there is less redundancy.

However, I can not find any information on how to specify that my data should use RRS rather than standard S3. In fact, there doesn't seem to be any website interface for an S3 services. If I log into AWS, there are only options for EC2, Elastic MapReduce, CloudFront and RDS, none of which I use.

Any insight?

Thanks.

Answer 1

All objects in Amazon S3 have a storage class setting. The default setting is STANDARD. You can use an optional header on a PUT request to specify the setting REDUCED_REDUNDANCY.

From: http://aws.amazon.com/s3/faqs/#How_do_I_specify_that_I_want_to_store_my_data_using_RRS

Answer 2

You can use S3 Browser to switch to Reduced Redundancy Storage. It allows you to view/edit storage class for a single file or for multiple files. Moreover, you can configure default storage class for the bucket, so S3 Browser will automatically apply predefined storage class for all new files you are uploading through S3 Browser.

If you are using S3 Browser to work with RRS, the following article may be helpful:

Note, Storage Class preferences are stored in a local settings file.Other s3 applications are using their own way to store bucket defaults and currently there is not single standard on this.

If you are looking for a way to convert existing data in amazon s3, you can use a fairly recent version of boto and a script I wrote. Details explained on my blog:
