#deduplication

This project offers a collection of scripts designed for text deduplication leveraging methods such as MinHash, SimHash, and SuffixArray Substring. It caters to handling large datasets with techniques like embedding-based detection and exact hashing. Suitable for developers seeking customizable and script-based solutions over general-purpose libraries, it ensures deduplication tasks are tailored. The project includes detailed documentation and examples for implementation, serving as a resource to enhance data quality by reducing redundancy.

Bees is a deduplication agent tailored for large btrfs filesystems, offering efficient offline deduplication and incremental data scanning to reduce disk usage time. It features space-efficient hashing, support for btrfs compression, and the ability to handle live data without causing downtime. Bees utilizes a persistent hash table for speedy restarts, albeit requiring root access and lacking file filtering capabilities. It's an effective choice for optimizing storage across entire filesystems, including snapshots, in btrfs environments.

DataTrove efficiently manages, filters, and deduplicates large-scale text data. It runs seamlessly across platforms including local machines and Slurm clusters, ideal for processing complex workloads such as large language model training datasets. With minimal memory usage and customizable functionality, DataTrove supports diverse file systems via fsspec, providing scalable and adaptable data processing pipelines.

BorgBackup offers a sophisticated solution for secure and efficient data backup. Utilizing content-defined chunking for deduplication, it minimizes storage needs by saving only changed parts of data, making it ideal for frequent backups. Users benefit from client-side 256-bit authenticated encryption, protecting data integrity and confidentiality even on untrusted backup locations. Additionally, Borg supports various compression methods to optimize storage further, and it allows for remote SSH backups and mountable archives, simplifying data retrieval. As a free, open-source software, Borg encourages community involvement and independent security audits. Please note the beta status of Borg2 and avoid using it for production backups to mitigate potential risks.
