Manent is an algorithmically strong backup and archival program. It features efficient backup to anything that looks like storage. Currently it supports plain filesystems ("directories"), FTP, and SFTP. Planned are Amazon S3, optical disks, and email (SMTP and IMAP). It can work (making progress towards finishing a backup) over a slow and unreliable network. It can offer online access to the contents of the backup. Backed up storage is completely encrypted. Backup is incremental, including changed parts of large files. Moved, renamed, and duplicate files will not require additional storage. Several computers can use the same storage for backup, automatically sharing data. Both very large and very small files are supported efficiently. Manent does not rely on timestamps of the remote system to detect changes.
JImageExplore is an image viewer with features to make navigating image archives simple. It extends JImageView, which is a plain image viewer, and adds a way to navigate directories and archive files. Thanks to TrueZIP, archive files are treated as virtual directories. JImage Explore also adds support for docking windows which will be used for supporting extensions such as multiple image display and thumbnail views.
ns4 is a command line configuration management tool that runs on a Unix or Windows based operating system. It allows the automated backup of node (i.e. routers and switches) configurations to an FTP/SFTP server or local media on a daily basis to create configuration archives. It can run ad-hoc commands on multiple nodes as well as custom scripts for automating complex tasks. It uses Perl and allows you to manipulate the output of commands using regular expressions within scripts. Configuration based cartridges are used to specify new node types, allowing the user to extend its functionality in a simple and dynamic way.
Tahoe-LAFS (Least Authority File System) is a decentralized data store. It distributes your filesystem across multiple servers, and even if some of the servers fail or are taken over by an attacker, the entire filesystem continues to work correctly and to preserve your privacy and security.
LBackup is a simple backup system aimed at systems administrators who require reliable backups with minimum fuss. It is configured with configuration files, and the backup is started from the command line. It has been tested for over 10 years. Backups can be to local media, or to remote media via one or more networks. The networks may be private LANs, WANs, or sets of untrusted public networks such as the Internet.
