Abstract

A data processing system and method, as well as a device, are provided. A storage device stores data copies in the form of a data backup chain. The data backup chain records data copies in the storage device in a time sequence of backing up the data copies in the storage device. Any data access instance has a data access function, and the data access instance can process a data access request. The data access instance can perform data backup and back up data in the storage space of the data access instance to the storage device as a data copy in the data backup chain. With the support of the storage device, the data access instance further has a data disaster recovery function and a data tiering function. The data processing system supports one or more multi-copy technologies, and the storage device only stores data copies in the form of a data backup chain, and does not need to store multiple data backup chains. This can effectively reduce the occupation of storage resources.
