Abstract

The embodiment of the invention discloses a data operation method and a data operation system, and particularly discloses a data de-duplication storage method. The data de-duplication storage method comprises the following steps of determining a target object and target hash values of the target object, judging whether or not the target hash values can be found in a corresponding relation of hash values and the number of storage times, if no, storing the target object based on the target hash values, adding a new corresponding relation of the target hash values and the number of target storage times to the corresponding relation of hash values and the number of storage times, and adding one to the number of the target storage times based on an initial value; if yes, not storing the target object, and adding one to the number of the target storage times corresponding to the target hash values in the corresponding relation of the hash values and the number of the storage times. According to the data operation method and the data operation system, a de-duplication storage process of the target object is provided, which can avoid repeated storage of the objects and guarantees that only one target object is stored in storage space, and therefore no storage space is wasted.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data operation method and system. Background technique [0002] Storage devices are ubiquitous in the computer field, and the storage devices provide data storage functions for users. Since a storage device can serve one user or multiple users, each user can store data in the storage device. [0003] In actual use, there will be a process for the user to store the same data on the storage device. Currently, the storage device will store one piece of data multiple times. This will waste the storage space of the storage device. Contents of the invention [0004] The present application provides a data operation method and system, which provides a deduplicated storage process for target objects, thereby avoiding repeated storage of the same object, thereby ensuring that only one copy of the target object is stored in the storage space, thereby saving storage space....
