Can I use Reduced Redundancy Storage with my S3 deployments?
Beanstalk supports the Reduced Redundancy Storage (RRS) option when deploying to Amazon S3. If you have not already, you can read about deploying to Amazon S3 in a separate help article.
When setting up an Amazon S3 server in Beanstalk, under the Advanced Options section you have an option to enable Reduced Redundancy Storage option. This will force Beanstalk to send all files to your Amazon S3 bucket with that setting turned on. It can save you money in the long run when storing assets that are easily replaceable, such as thumbnails for images.
Please note that enabling RRS for a server to which you have deployed before will not affect the files that were already uploaded to the bucket. For this reason Beanstalk will ask you if you want to deploy from scratch after you enable the RRS option. Deploying from scratch in that case will enable RRS for existing files in your bucket.
To find out more about RRS, check the official documentation.
