Problems solved by technology

However, with the continuous increase of users and data, the repetition rate of data is getting higher and higher, and the speed of data erasure and rewriting is getting faster and faster, resulting in a decrease in the utilization rate of cloud storage resources, a serious loss of disk life, and a large occupation network bandwidth
Some cloud service providers use the data deduplication mechanism on the cloud storage system, but as the amount of data continues to increase, the load of data deduplication verification on the cloud storage system is also increasing

Embodiment Construction

[0023] The present invention will be described in further detail below according to accompanying drawing, and concrete realization mechanism is as follows:

[0024] Such as figure 1 as shown,

[0025] Step 1: Collect the data that the customer needs to back up on the cloud service client;

[0026] Step 2: The cloud service client software has a data verification function. When the software receives a file backup request, it will first verify the file, obtain the file Hash code, and then send the Hash code to the cloud storage system; because the hash code The amount of data is only a few KB, so it will not take up too much bandwidth between the cloud storage system and the backup client;

[0027] Step 3: After receiving the Hash code sent by the client software, the cloud storage system will check whether the file has been backed up in the system's backed up file archives. This verification value is compared with the hash value generated by the previously backed...

Abstract

The invention provides a backup mechanism for repeating data deleting of a cloud service, and belongs to the field of cloud storage service data backup. According to the backup mechanism, a data repeating deleting mechanism is carried out on a cloud service end, data are stored to a cloud storage pool in a unification mode, and only a file pointer is set in a personal folder of a client. The bandwidth pressure occupied by data uploading is greatly relieved, the load, for carrying out data repeating deleting, of a cloud storage server is reduced, and the storage cost is saved.

Description

[0001] technical field [0002] The present invention relates to the field of cloud storage services, in particular to a duplicate data backup mechanism for cloud services, which can greatly reduce the load on cloud storage servers, ease the pressure on network bandwidth, and greatly improve the space utilization rate of cloud storage disks and the service life of disks . Background technique [0003] Cloud services are Internet-based accretion, usage, and delivery models of related services, usually involving the provision of dynamically scalable and often virtualized resources over the Internet. Cloud is a metaphor for network, internet. In the past, the cloud was often used to represent the telecommunications network in the figure, and later it was also used to represent the abstraction of the Internet and the underlying infrastructure. Cloud services refer to obtaining required services through the network in an on-demand and easy-to-expand manner. Such services can...
