Abstract

The invention discloses a deduplication rate calculation method, which comprises the following steps: obtaining a file operation request, executing the file operation request by utilizing an online deduplication method, generating corresponding log information, and adding the log information into a log; reading a log, and calculating a theoretical occupancy value of the storage system; and acquiring an actual occupancy value of the storage system, and calculating a deduplication rate by utilizing the theoretical occupancy value and the actual occupancy value. The deduplication rate calculationmethod executes a request by utilizing an online re-deletion method after obtaining an execution file operation request, generates the corresponding log information, calculates the theoretical occupancy value of the storage system by utilizing the log when the deduplication rate is calculated, calculates the deduplication rate of the storage system by utilizing the theoretical occupancy value andthe actual occupancy value, does not need to stop the receiving service operation, can accurately calculate the deduplication rate of the storage system at the current moment, and can improve the accuracy of the deduplication rate calculation. In addition, the invention also provides a deduplication rate calculation apparatus and device and a computer readable storage medium, which also have theabove beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of file deduplication, and in particular to a deduplication rate calculation method, a deduplication rate calculation device, a deduplication rate calculation device, and a computer-readable storage medium. Background technique [0002] Storage space is a limited resource. Different files uploaded by the same user, such as logs at different times, or files uploaded by different users, such as files uploaded by different people from the same company, will contain a large number of files with the same content. files or objects with the same content after splitting. To save storage space, data deduplication can be performed on the storage cluster. After the deduplication function is enabled, it is very important to count the deduplication rate to measure and compare the efficiency and performance of different deduplication algorithms, algorithm optimization configuration parameters, and algorithm imple...
