SNeBU (Simple Network Backup Utility) is a backup system that supports incremental snapshot-style backups to disk-based storage. The project has been rewritten in C, and stores its backup catalog in an SQLite database. It features file level deduplication (including across multiple clients), compressed storage, incremental-forever snapshot style backups, simple setup, and utilizes standard TAR format. The client side consists of a simple shell script, which can be easily installed and adapted as needed. The server side is a single binary plus a config file, which can sit on a remote server and be accessed over SSH.
Collax Business Server is an all-in-one Linux server for small- and medium-sized businesses. It delivers all the important network services within a heterogeneous business environment for communication, infrastructure, compliance, groupware, and storage, all in a reliable and secure way which is easy to manage. It also provides essential security functions such as firewalling and virus and spam filtering, to protect against hacker attacks, viruses, and unsolicited email messages.
Libchop is a set of utilities and library for data backup and distributed storage. Its main application is chop-backup, an encrypted backup program that supports data integrity checks, versioning at little cost, distribution among several sites, selective sharing of stored data, adaptive compression, and more. The library itself, which chop-backup builds upon, implements storage techniques such as content-based addressing, content hash keys, Merkle trees, similarity detection, and lossless compression. It makes it easy to combine them in different ways. The ‘chop-archiver’ and ‘chop-block-server’ tools, illustrated in the manual, provide direct access to these facilities from the command line. It is written in C and has Guile (Scheme) bindings.
SafeHaven provides a new approach to backup. The basic idea is to store contents away once and forever. No two copies of the same contents will be saved by SafeHaven unless they are presented in two different formats, and even then, SafeHaven attempts to be as smart as possible, and will recognize the most common formats, including compressed files, archives, and ISO image files.
