Embodiment 1

[0059] This embodiment will be described from the perspective of the client, the data stored by the client exists in the form of data blocks, and the client may specifically be a SAN system. The application scenario of this embodiment is as follows Figure 16 As shown, the client includes a production host 1601 and a storage array 1602 connected to the production host 1601 , and the storage array 1602 is connected to a cloud center 1604 through the Internet 1603 . The production host 1601 stores the generated data in the storage array 1602, and the storage array 1602 backs up the data to the cloud center 1604 through the Internet.

[0060] like figure 2 As shown, this embodiment provides a method for uploading data to the cloud, which includes:

[0061] 201. A storage area network (SAN) system converts a data block to be backed up into an object and generates an identifier for identifying the object.

[0062] 202. The SAN system uploads the object and the object identifier...

Embodiment 2

[0075] like image 3 As shown, this embodiment provides a method for uploading data to the cloud, which includes:

[0076] 301. Divide the logical volume in the SAN system into a predetermined number of zones, and each zone contains a predetermined number of data blocks.

[0077] 302. Merge and convert the data blocks in the same area into an area object corresponding to the area, wherein, according to the numbering order of the data blocks in the same area, store the data of the data blocks in the same area in the area object.

[0078] Since the data of data blocks in the same area are stored in the order of data block numbers, when it is necessary to search for the data of a certain data block from the cloud storage object, you can , determine the location where the data of a certain data block is stored in the zone object, that is, the data corresponding to a certain data block can be found in the zone object.

[0079] 303. Generate an identifier for identifying the zone...

Embodiment 3

[0092] like Figure 4 As shown, this embodiment provides a method for cloud backup data, including:

[0093] 401. The cloud obtains a zone object corresponding to the zone uploaded from the storage area network (SAN) system. The SAN system includes a logical volume, the logical volume is divided into a predetermined number of areas, each area contains a predetermined number of data blocks, and the uploaded area object includes a changed one or Multiple data blocks are merged and converted, wherein the data of each changed data block is stored in the uploaded area object according to the serial number of the changed data blocks.

[0094] The cloud may be a cloud center, specifically a cloud server.

[0095] 402. The cloud further obtains an object file corresponding to the zone object uploaded from the SAN system. The object file includes the identifier for identifying the area object, the size information of the data blocks in the same area, and the number of each changed d...

Abstract

The invention discloses a method for uploading data to cloud. The method comprises the steps that a storage area network (SAN) system converts data requiring to be backed up into objects and generating identifiers used for identifying the objects; and the SAN system uploads the objects and the identifiers of the objects to the cloud. The method solves the cloud backup problem of data stored in the form of data blocks in a client, the cost of data backup is reduced, and the backup demand of mass data is met. The invention also provides a corresponding method for searching, backup and recovery of data, and the corresponding client and cloud.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to methods and devices for uploading, cloud backup, searching and restoring data. Background technique [0002] With the continuous development of information science and technology, the wide application of the Internet, and the continuous popularization of cloud computing, the amount of data storage is growing rapidly at an alarming rate. However, while the amount of data storage is increasing, the problem of data storage security is also becoming more and more prominent. In order to avoid losses caused by damage and loss of stored data, it is generally necessary to back up the stored data. [0003] Currently, some enterprise users need to back up data stored in a storage area network (Storage Area Network, SAN) system in the form of chunks. SAN system is a centralized management high-speed storage network composed of storage system, storage management software, applicatio...
