S1. Obtain file information;

In the embodiment of the present application, the file information is information of a user's uploaded file, wherein the user's upload file is a user file of a user that is uploaded and stored, and the user file is one or more files. In the embodiment, in order to reduce the storage cost, it is necessary to perform hierarchical storage on the uploaded user files. Different companies store the uploaded user files in different storage pools in the order of upload time according to their respective data storage capabilities, such as: The current time is the benchmark. User files whose upload time is within 30 days of the current time are stored in the high-speed storage pool, with fast access speed and high storage costs. User files whose upload time is more than 30 days away from the current time are transferred to the low-speed storage pool. In the storage pool, the access speed is slow, but the storage cost is low. Further, the information of the user file includes: file information, file access information, file storage address, and file upload time. The file information is the file names of all files in the uploaded user file, the file access information is the daily access times of all files in the uploaded user file, and the file storage address is each file in the uploaded user file. The file upload time is the upload time of each file in the uploaded user files. If file A was uploaded on December 4, 2020, the upload time is December 4, 2020. Specifically, for example, in the uploaded file information of user A, the file information is file A and file B, the file access information is the number of times that file A and file B are accessed every day, the file storage address is the storage path of file A and file B, and the file storage address is the storage path of file A and file B. The upload time is December 4, 2020 when the A and B files were uploaded.

S2, extracting the file access information in the file information, and using the file access information to perform an association calculation to obtain a file association value set;

File association value set; wherein, the file access information is the daily access times of each file in the uploaded user files, such as: User A uploads file A and file B, and the file access information of user A is file A and file B The number of visits per day.

In detail, in this embodiment of the present application, using the file access information to perform file association calculation to obtain a file association value set includes: using the file access information to calculate the sample standard deviation and the value of each file in the file access information. The sample covariance of two files; calculate the correlation value of any two files in the file access information according to the sample standard deviation and the sample covariance, and summarize all the correlation values to obtain the file correlation value set.

Wherein, the sample standard deviation can be calculated by the following formula:

Wherein, S _x is the sample standard deviation of the x file, x _i is the number of visits per day of the user file x in the file access information,

is the average of the daily access times of x files, n is the total number of days that x files are uploaded, i is the date, and x is the file of the user in the file access information.

Therefore, file B and file C are transferred to the high-speed storage pool to access the file. The speed of file B and file C will be very fast. If file B and file C are not accessed for a period of time, file B and file C will be transferred to the low-speed storage pool to reduce file storage costs.
