How to Set Reduced Redundancy Storage (RRS) for S3 with CrossFTP

Reduced Redundancy Storage (RRS) is a 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. RRS provides a lower cost, less durable, highly available storage option that is designed to sustain the loss of data in a single facility.

CrossFTP supports the Reduced Redundancy Storage (RRS) configuration for S3 for newly uploaded files and existing files. For existing files you already uploaded on S3, you can find their storage classes by right click on the file pane's column head, and toggle Storage Class from the popup menu. This is shown in Fig. 1.

Here are the instructions for setting up the RRS:

• New Files - for new files you prepare to upload to the S3, you can toggle Sites -> Site Manager -> S3 -> Reduced Redundancy Storage (RRS), and then all new uploaded files will be in RRS storage class. This is shown in the Fig. 2.

• Existing Files -if you want to convert the existing files' storage class, you can choose the files/folders in the file pane, and select right click and choose Properties... -> Metadata from the popup dialog. After that, press + button, and select Key as x-amz-storage-class, and Value as REDUCED_REDUNDANCY for RRS, or STANDARD for default S3 class storage. Press OK button to save, and Commit button to submit the changes. This is shown in Fig. 3.
