rdiff-backup is a backup software written in Python that creates reverse incremental backups.The most recent backup is thus directly accessible, while earlier backups will be reconstructed from diff files by rdiff-backup.
Dictionary Builder is a Rust program that can parse XML dumps and extract entries in files; Scripts for parsing Wikipedia dumps – Python based scripts for parsing sql.gz files from wikipedia dumps. parse-mediawiki-sql – a Rust library for quickly parsing the SQL dump files with minimal memory allocation
The delta file can then be applied to file A, turning it into file B (similar to the patch utility). rdiff works well with binary files. The rdiff-backup script maintains a backup mirror of a file or directory either locally or remotely over the network on another server. rdiff-backup stores incremental rdiff deltas with the backup, with which ...
Duplicity operates under a scheme where the first archive is a complete (full) backup, and subsequent (incremental) backups only add differences from the latest full or incremental backup. [4] Chains consisting of a full backup and a series of incremental backups can be recovered to the point in time that any of the incremental steps were taken ...

A delta can be defined in 2 ways, symmetric delta and directed delta.A symmetric delta can be expressed as (,) = (),where and represent two versions.. A directed delta, also called a change, is a sequence of (elementary) change operations which, when applied to one version , yields another version (note the correspondence to transaction logs in databases).

Commonly done by calculating and storing hash function digests of files to detect if two files with different names, edit dates, etc., have identical contents. Programs which do not support it, will behave as if the originally-named file/directory has been deleted and the newly named file/directory is new and transmit the "new" file again.
