Abstract: The objective of the present invention is to provide a method, apparatus, system, computing device and computer-readable medium for data migration between cloud storage systems. Here, a user equipment generates, according to a list of to-be-migrated files, descriptive information of each file in the list; and transmits one or more data migration requests to available server(s), respectively, such that the corresponding server performs data migration between different cloud storage systems, wherein each data migration request includes indication information of a source end and a destination end of the data migration and descriptive information of one or more to-be-migrated files. The present invention may satisfy various performance requirements on performance, flexibility, scalability, automation, data verify and framework universality, etc.

Abstract: Some embodiments disclose a method and apparatus for processing data, a computer device and a storage medium. A method can include: acquiring, by a cloud storage system, a series of slices obtained by dividing a to-be-stored file; encrypting, by the cloud storage system, each slice by using a different data key; and storing, by the cloud storage system, an encrypted data ciphertext.
