Open Source Archiving Software

DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing, supports differential backup with or without binary delta, ftp and sftp protocols to remote cloud storage Archive internal's catalog, allows very quick restoration even a single file from a huge, eventually sliced, compressed, encrypted archive eventually located on a remote cloud storage, by only reading/fetching the necessary data to perform the operation. Dar saves *all* UNIX inode types, takes care of hard links, sparse files as well as Extended Attributes (MacOS X file forks, Linux ACL, SELinux tags, user attributes) and some Filesystem Specific Attributes (Linux ext2/3/4, Mac OS X HFS+) more details at: http://dar.linux.free.fr/doc/Features.html

ReHash is an easy-to-use console-based hash calculation tool written in C++. It supports many algorithms and output formats and it can be fully configured using some of the many command-line arguments which can be passed to the tool.

HashSum is a .NET port from GNU's md5sum and sha1sum. It supports: hash algorithm selection between MD5 and SHA1 (more could be added later) and compatibility between HashSum and GNU's checksum file format

Backup P2P is a peer to peer application doing automated and secured backups inside a community (Jabber, XMPP). Each user shares some available space on his disk with others, to be able in return to remotely backup some of his own data.

Bork is a very small, cross-platform file encryption utility. It is written in Java and designed to be included along with the files it encrypts for long-term storage (eg on CD-R). Its minimal external dependencies make it fairly futureproof.

How do you find anything in the mountain of data on your PC? How do you organise, maintain, archive and protect your files? How do you avoid surrendering to the Powers of Darkness? Checkpoint Commander, the vital tool for Information Management!

Use of Michael Rabin's Information Dispersal Algorithm to provide secure, dispersed storage in a networked environment. For full download, please get both Math-FastGF2 and Crypt-IDA releases under the files link. See project wiki for more information.

INTIX-JSIGNER is a java web application for signing documents (XML and/or PDF) of unattended way and in the server side. It has as main modules the following: Authentication, XML and PDF Signing and Keys and Certificates Management.

Open Legacy Storage Document: Generic Document Archiving on Disk and Network(using MINA) Framework in Java for huge number of docs(up to 2^192 documents), efficient(Java NIO), crypto, net transfert, web retrieve, J2EE and eMail archiving compatible.

A program to calculate and verify checksums of multiple files with wizard-like GUI. Supports 12 hashes: CRC32, MD2, MD4, MD5, SHA1, SHA2, RIPEMD,Whirlpool, ED2K, AICH, Tiger, TTH. Allows processing of nested directories and updating of checksum files

The RAZip bitstream format was designed to provide a faster random access to compressed data than what is currently possible using the GZIP format. During the desing phase, some other features were added, like encryption and error correction.

partitioning backup recovery and all kind of boot loaders

A plattform independent encryption-tool with a simple user interface (swing/java). It uses 'Password Based Encryption' (PBE) to encrypt and/or decrpyt files on the filesystem. Encryted files will also be compressed using the zip-format.
