Embodiment 1

[0053] An embodiment of the present invention provides a method for copying data, which is applied to a storage controller, and the storage controller is connected to a primary storage device and at least one secondary storage device, such as figure 1 shown, including:

[0054] S101. A storage controller acquires attribute information of at least two pieces of data to be backed up stored in a primary storage device.

[0055] Specifically, the attribute information of each data to be backed up includes at least one of the following information:

[0056] The source information, write time information, write times information, read time information, read times information, storage structure information and storage location information of the data to be backed up.

[0057] S102. The storage controller determines the importance scoring scores of the at least two data to be backed up according to the attribute information and a preset scoring rule.

[0058] Wherein, the scoring ru...

Embodiment 2

[0092] An embodiment of the present invention provides a storage controller 30 for implementing the data copy method provided in the first embodiment above, wherein the storage controller 30 is connected to a primary storage device and at least one secondary storage device, such as image 3 As shown, the storage controller 30 includes:

[0093] The first obtaining unit 31 is configured to obtain attribute information of at least two pieces of data to be backed up stored in the main storage device;

[0094] The first determining unit 32 is configured to determine the importance scoring scores of the at least two data to be backed up according to the attribute information acquired by the first acquiring unit 31 and the preset scoring rules;

[0095] The second acquiring unit 33 is configured to acquire a score threshold; the score threshold is greater than the lowest importance score of the at least two data to be backed up, and smaller than the highest importance score of the a...

Embodiment 3

[0120]The embodiment of the present invention provides another storage controller 40, the storage controller 40 is connected with the master storage device and at least one slave storage device, such as Figure 4 As shown, the storage controller 40 includes:

[0121] Processor (processor) 41, communication interface (Communications Interface) 42, memory (memory) 43 and communication bus 44; Wherein, described processor 41, described communication interface 42 and described memory 43 complete by described communication bus 44 mutual communication.

[0122] The processor 41 may be a multi-core CPU, or an ASIC (Application Specific Integrated Circuit), or one or more integrated circuits configured to implement the embodiments of the present invention.

[0123] The memory 43 is used to store program codes, which include computer operation instructions and network flow diagrams. The memory 43 may include a high-speed RAM memory, and may also include a non-volatile memory (non-vol...

Abstract

The invention discloses a data copying method and device, relating to the field of computers. According to the data copying method and device, the problem that only the data with relatively high importance and the data with relatively low importance can be simultaneously copied during the data copying in the prior art is solved. The method comprises the following steps: acquiring attribute information of at least two to-be-copied data stored in a main storage device by virtue of a storage controller; determining importance rating scores of the at least two to-be-copied data according to the attribute information and a preset scoring rule; acquiring a score threshold, carrying out numeric comparison on the importance rating scores of the at least two to-be-copied data and the score threshold, so as to determine critical data and non-critical data in the at least two to-be-copied data; and preferentially copying the critical data into at least one slave storage device, and copying the non-critical data into the at least one slave storage device after the critical data is copied. The embodiment of the invention is applied to data copying.

Description

technical field [0001] The invention relates to the field of computers, in particular to a data copying method and equipment. Background technique [0002] Currently, in order to ensure the safety and reliability of data on a storage device, one or more secondary storage devices are usually set up for the storage device, and the data in the storage device is copied to the secondary storage device for backup at regular intervals or in real time. [0003] In the prior art, when data is backed up, the logical partition or the file system presented by the data in the storage device is often copied as a whole. [0004] When backing up the data in the storage device, for the data stored in the storage device that is more important to the user, the user needs to back up the data of higher importance first. However, since data with high importance and data with low importance may be stored in a logical partition or file system at the same time, the prior art can only backup data wi...
