Abstract

The invention relates to a data processing method and a system, a computer device and a computer storage medium in a repetitive data deletion process. The method comprises the following steps: extracting file data of a first data amount from the backup data, detecting whether the file data conforms to a preset partitioning condition; if the file data does not conform to the partitioning condition,extracting the file data of the second data amount from the backup data, superimposing the extracted file data on the file data extracted before the extracting, and obtaining the superimposed data; if the superimposed data does not conform to the partitioning condition and the data amount of the superimposed data is smaller than the third data amount, returning the file data extracting the seconddata amount from the backup data, superimposing the extracted file data on the file data extracted before the second data amount, and obtaining the superimposed data; if the superimposed data meets apreset block partitioning condition or the data amount of the superimposed data is greater than or equal to the third data amount, the current superimposed data is determined as a re-deleted data block.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data processing method and system, computer equipment, and computer storage medium in the process of data deduplication. Background technique [0002] De-duplication is a data reduction technology designed to reduce the storage capacity used in a storage system. It eliminates redundant data by deleting duplicate data in the storage system and retaining only one copy. The space-saving efficiency of deduplication technology can be characterized by the deduplication rate, which can be determined according to the ratio between the size of the saved space and the size of the original data. [0003] Data deduplication technology can be divided into file level and data block level according to granularity. Data block-level deduplication divides a file into data blocks in different ways, and detects data blocks as units; data block methods in data block-level deduplic...
