Abstract

The invention discloses a file storage method, comprising: performing strip processing on a target file to obtain a plurality of target objects, and calculating the fingerprint information of each target object; using the logical information of the first target object and the target file to form a logical header object , and store the logical head object in the storage system; use the fingerprint information of each second target object to judge whether the second target object has been stored in the storage system; if the second target object has not been stored in the storage system, then The second target object is determined as the third target object and stored in the storage system; this method stores the logical header objects of all files in the storage system, and since the logical header objects are all stored in the storage system, each file can be preserved logical information, avoiding the modification or even deletion of some users’ files after deduplication in the storage system; in addition, the present invention also provides a file storage device, equipment, and computer-readable storage medium, which also have the above-mentioned beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of object storage, in particular to a file storage method, a file storage device, a file storage device, and a computer-readable storage medium. Background technique [0002] Distributed object storage system refers to distributed storage for unstructured data. At this stage, more and more business scenarios need to use distributed object storage systems. How to eliminate duplicate data in the storage system and improve storage usage efficiency when uploading data to the storage system is becoming more and more important. [0003] In the current distributed object storage system, while the logical head object carries the data content, it is also associated with metadata. The file fingerprint of the overall file is used as an identifier to participate in deduplication. Metadata includes user permissions, object deletion time, etc. Metadata properties. After deduplication is enabled in the storage sy...
