Abstract: A storage device stores a data copy in a 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 to 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 may perform a data backup, and back up data in storage space of the data access instance to the storage device as a data copy in the data backup chain. With support of the storage device, the data access instance further has a data disaster recovery function and a data tiering function.

Abstract: A data processing method includes a computing device that obtains first data, and determines a deduplication rate of the first data and a working status of the computing device. When the working status of the computing device is a busy state, and when the deduplication rate of the first data is greater than or equal to a first preset value, deduplication on the first data is performed. When the deduplication rate of the first data is lower than the first preset value, deduplication is not performed on the first data, and the first data may be directly stored.

Abstract: This application provides a data backup system and an apparatus. The system includes a data processing apparatus and a storage device. The data processing apparatus is configured to receive a write request sent by a first host, where the write request carries first data that needs to be backed up to the storage device. The data processing apparatus is configured to perform deduplication and compression operations on the first data, to obtain second data. The data processing apparatus is further configured to write the second data into the storage device.
