A data storage method and a data storage management server

Abstract

The invention discloses a data storage method: when receiving a storage request for any data block x, determine the initial storage number of data block x, and store the data block x according to the initial storage number; Perform the following processing selectively: determine the current importance level of data block x, and determine whether the storage shares corresponding to the importance level are the same as the current storage shares of data block x, and if not, then store the current storage shares of data block x The number is adjusted to be the same as the number of stored shares corresponding to the importance level; wherein, the higher the importance level, the larger the corresponding stored shares, and the lower the importance level, the smaller the corresponding stored shares. The invention also discloses a data storage management server. By applying the scheme of the present invention, storage resources can be reasonably utilized.

Description

technical field [0001] The invention relates to data processing technology, in particular to a data storage method and a data storage management server. Background technique [0002] In the prior art, when data is stored, data backup is usually performed on stored original data. [0003] Data backup refers to copying or copying the original data and storing it separately. When the original data is lost or damaged due to hardware failure, virus, human factors, etc., the backup data is used to restore the original data. [0004] In order to improve data reliability, etc., it is usually necessary to increase the number of backup copies. However, when there are a lot of original data to be backed up, if the original data is not distinguished according to the importance level and a fixed number of copies are backed up, the storage resources will be insufficient. Reasonable use. [0005] For example, if the fixed number of copies is 2, then the original data with a higher level ...

Problems solved by technology

[0004] In order to improve data reliability, etc., it is usually necessary to increase the number of backup copies. However, when there are a lot of original data to be backed up, if the original data is not distinguished according to the importance level and a fixed number of copies are backed up, the storage resources will be insufficient. Reasonable use

[0005] For example, if the fixed number of copies is 2, then the original data with a higher level of importance and the original data with a lower level of importance will all be backed up in 2 copies, and for the original data with a higher level of importance, the backup copy The number of backup copies will be too small, but for the original data with low importance level, the number of backup copies will be too many, resulting in unreasonable utilization of storage resources
