+S3 storage driver support
+=========================
+
+* https://blueprints.launchpad.net/freezer/+spec/s3-driver-support
+
+Provide more storage media options for users to store the backup data.
+
+Problem description
+===================
+
+Currently, freezer can only store backup data to swift compatible object
+storage (except local and ssh), so we should increase support for other storage
+driver. S3 compatible object storage is a valid choice, which is used by many
+individuals and companies in the public or private clouds. With S3 driver,
+freezer can store backup data in S3 compatible object storage, such as AWS S3
+or ceph S3 interface.
+
+Use Cases
+---------
+
+* Users that want to backup data to S3 compatible object storage.
+
+* OpenStack distributions deployed without swift module.
+
+Proposed change
+===============
+
+Implement in the freezer-agent a new storage type called 's3'.
+
+With specifying the 's3' storage type, the authentication parameters and the
+S3 endpoint, backup data will be stored on S3 compatible storage after the
+backup finished.
+
+Alternatives
+------------
+
+None
