Method for carrying out seamless migration of simple storage service by using index object, master device and storage server

A method for performing Simple Storage Service (S3) seamless migration using index objects and associated apparatus are provided. The method includes: in response to a request of migrating user data of a user of the storage server from a remote S3-compatible server into the storage server, during an index stage, utilizing an index-object-based S3 migration management module among multiple program modules running on a host device within the storage server to create and store multiple index objects into a storage device layer of the storage server to be respective representatives of multiple normal objects of the user data at the storage server, and migrate respective Access Control Lists (ACLs) of the multiple normal objects to the storage server to be respective ACLs of the multiple index objects; and during a data stage, utilizing the index-object-based S3 migration management module to trigger one or more migration agents to migrate object data. 本发明公开了一种利用索引物件来进行简易存储服务无缝迁移的方法以及相关设备，该方法包含有：因应自远端简易存储服务相容服务器迁移
