In Linux, par2 is an error correction tool used to create and repair redundant checksums of data files to protect data from damage or loss. When a Par2 file is created, it is based on the original The data creates some redundant blocks, which contain the verification and error correction information of the original data file.

In Linux, par2 is an error correction tool and is also the abbreviation of Parity Archive Volume Set. It is used to create and repair redundant checksums of data files to protect data from corruption or loss.

Par2 files are usually used together with raw data files, and their purpose is to increase the fault tolerance of the data. By creating redundant data blocks, redundant information generated from the original data, Par2 files enable you to repair when the original data file is damaged or partially lost.

When you create a Par2 file, it creates some redundant blocks based on the original data. These redundant blocks contain verification and error correction information for the original data file. If an error occurred or the original data file was deleted, you can use Par2 files to recover the corrupted data. By using known redundant information, the Par2 tool can calculate and repair errors or missing portions of the original data file.

For any situation involving important data, such as storing, transferring or backing up files, using the par2 tool can provide a certain degree of data integrity and redundancy check protection. You can use the par2 command line tool to create and repair Par2 files, and there are some graphical interface tools that provide similar functionality.
