Example Embodiment

[0050] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0051] First, explain the terms in the embodiments of this application:

[0052] Video cloud storage: In the security industry, video data needs to be continuously stored in chronological order and cyclically covered according to a certain period or capacity. However, traditional file storage methods have certain differences in the characteristics of video streaming storage. The video cloud storage data storage method simplifies the storage process and ...

Abstract

Embodiments of the invention provide a storage block data deletion method and device, electronic equipment and a cloud storage system. The method comprises the steps of obtaining a target moment and ablock final write-in moment of each storage block; determining a target storage block of which the final writing moment is smaller than the target moment, and deleting data in the target storage block; obtaining the final writing moment of the video segment of the video segment in each storage block; judging the sizes of the final writing moment and the target moment of each video segment; deleting the video segment with the final writing moment smaller than the target moment. According to the storage block data deleting method, when the storage space of the resource pool is cleaned, the video segment with the final writing moment smaller than the target moment is deleted, the video segment serves as the minimum detection unit, release of the storage space in the resource pool can be increased, and the effective utilization rate of storage resources is increased. Meanwhile, the time span of data in the same storage block can be reduced, and time updating of the resource pool is facilitated.

Description

technical field [0001] The present application relates to the technical field of data storage, in particular to a storage block data deletion method, device, electronic equipment and cloud storage system. Background technique [0002] In the existing cloud storage system, storage resources are managed through a virtualized resource pool, and its overall architecture is as follows: figure 1 shown. The cloud storage system includes management nodes and storage nodes. The storage nodes are the physical media for storing data. The block devices on the storage nodes are divided into storage blocks according to a fixed size. Logically manage the storage blocks. [0003] Resource pools are divided into covered pools and non-covered pools according to user needs. The overlay pool will reclaim space according to the policy. Specifically, in the coverage pool, the data in the storage block whose last write time is before the specified target time is cleared in units of storage blo...
