Problems solved by technology

[0002] With the development of information technology, data information is growing at an explosive rate, and people's demand for data storage capacity is also increasing, and this explosive demand growth also brings a lot of data redundancy. This is not only a waste of storage media, but also not conducive to meeting the storage requirements in network applications. Therefore, new technical solutions need to be proposed to reduce the large amount of data redundancy generated by large amounts of data storage.
However, so far, no practical solution to significantly reduce data redundancy has been found

Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings, and the accompanying drawings are only for illustration, not for limiting the patent scope of the present invention.

[0013] For most existing block storage media, the present invention provides a method for reducing data redundancy. The block storage medium mainly accesses the storage medium in units of blocks, and addresses the storage medium in a linear manner. For example, if a block size is 512k, the block with the address of 1 actually represents the data of 0 to 524288 bytes of the storage medium. And address 2 represents 524289~1048577 bytes of data, and so on. . . The method of the present invention constructs the original entire linear block data storage space into two parts, the access area and the public storage area. Wherein the access area includes a linear address table of the actual data stored. The linear address table is composed of metadata pointe...

Abstract

The method of reducing data redundancy in storage medium is used in solving the problem of excessive data redundancy in storage medium. The method includes dividing the space of the storage medium block into two parts of access region and public storing region, and storing practical block data in the public storing region. The access region includes one linear address list comprising address pointers, each of the pointers point one storage address of the some practical data in the public storing region, and several pointers may point the same data address. The method can avoid the repeated storing of the same data block.

Description

technical field [0001] The invention relates to data storage technology, in particular to a method for reducing data redundancy in data storage of block storage media. Background technique [0002] With the development of information technology, data information is growing at an explosive rate, and people's demand for data storage capacity is also increasing, and this explosive demand growth also brings a lot of data redundancy. This is not only a waste of storage media, but also not conducive to meeting storage requirements in network applications. Therefore, new technical solutions need to be proposed to reduce the large amount of data redundancy generated by large-scale data storage. However, so far, no practical scheme to significantly reduce data redundancy has been found. Contents of the invention [0003] In view of the above-mentioned defects of the existing data storage technology, the purpose of the present invention is to solve the problem of excessive data red...
