Problems solved by technology

[0005] In order to solve the problem that popular data in the prior art is processed offline, the present invention discloses a method and device for dynamically adjusting storage of space science and application data files, which can be judged by analyzing the activity level of data or online time. Delete data to eliminate data files that are not frequently used, and extend the storage time of frequently used data files on the server to meet the needs of space science and application data sharing services and maximize the value of data applications and research

Embodiment Construction

[0031] The method and device for dynamically adjusting space science and application data file storage of the present invention will be explained and illustrated in detail below in conjunction with the accompanying drawings.

[0032] Such as figure 1 , 2 , 3, and 4, the present invention discloses a method for dynamically adjusting space science and application data file storage, the method comprising the steps of:

[0033] Step 1, numbering all data files on the storage medium; in this embodiment, after traversing and reading all data files in the storage medium, and numbering all data files.

[0034] Step 2, in the process of using the data sharing service of space science and application data, the user sorts the numbers corresponding to all data files according to the activity level of each data file; in this embodiment, the activity level includes application frequency, download times and Online time, etc., so this embodiment normalizes the factor values ​​corresponding ...

Abstract

The invention discloses a method and device for dynamically adjusting space science and application data file storage. The method comprises the following steps that all data files on the storage medium are numbered; according to the degree of activity of each data file, the corresponding numbers of all the data files are sequenced; when the data files need to be cleaned, the data files are cleaned according to the sequencing result of the data file numbers. The device comprises a numbering module, a sequencing module and a cleaning module in sequence. By means of the method and device for dynamically adjusting space science and application data file storage, according to the activity degrees of the data files, the data files with low activity degrees are selectively processed offline, the data files which are not frequently used are eliminated, the time of the data files, which are always used, on a server is prolonged, the space science and application data sharing service requirement is met, and application and research value of data is given full play to greatly.

Description

technical field [0001] The present invention relates to the technical field of data storage, more specifically, the present invention is a method and device for dynamically adjusting storage of space science and application data files. Background technique [0002] At present, for the storage management of the FTP server of space science and application data, a fixed time period is adopted, that is, a fixed time period is set, and the expired data is processed offline to free up the corresponding server storage space. [0003] However, the above method will cause some popular data and unpopular data to be processed offline together, and the popular data processed offline at the same time will be requested to be downloaded again by the user to a large extent, which brings a lot of inconvenience to the data sharing user service. [0004] Therefore, for the existing management methods of server data, how to avoid reasonably deleting server data according to user needs and meet ...
