Abstract

Provided are a method, device and system for recovering a space on an online hard drive. The method comprises: a data server receiving a space recovering request, wherein the space recovering request is used to instruct recovering of a storage space containing data to be removed (S602); the data server querying a preset storage list group corresponding to the data to be removed to obtain a storage stripe group containing the data to be removed (S604); the data server performing, according to data not yet removed from the storage stripe group, grouping on storage stripes in the storage stripe group to obtain a storage stripe containing the data not yet removed (S606); the data server generating, according to the storage stripe, a space recovering command, and transmitting the space recovering command (S608); and the data server receiving space recovering response information (S610). The method, device and system of the invention solve a technical problem in which prior art techniques only involve performing data erasure operations on garbage data blocks without addressing the issue of how to improve data storage and management efficiency in a data movement process.

Description

technical field [0001] The invention relates to the application field of communication technology, in particular to a method, device and system for recovering network hard disk space. Background technique [0002] With the development of network technology, the concept of storage in the conventional sense has also been updated. Among them, virtual storage concepts such as network hard disk and cloud disk have expanded the storage types of storage technology. [0003] Computer local storage, that is, the local solid-state disk of the computer performs data reading and writing functions through I / O and the host computer. Different from computer local storage, in the application process of network hard disk, taking data upload as an example, the user uploads the local data in the user's physical computer to the virtual storage provided by the network server by accessing the network server; During the retrieval process, the user downloads the corresponding file data from the vi...
