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

Advanced archiver (zpaq fork) with deduplication and versioning. Never prune your backups: keeps a forever-to-ever copy (even thousands of versions) of your files, conceptually similar to Mac time machines, or zfs' snapshots, but much more efficiently. Ideal for virtual machine backup and "freezing" zfs snapshots forever. Easily handles millions of files and TBs of data. Allows rsync backups to the cloud (or NAS, or USB) with minimal data transfer, encryption and very limited bandwidth. Highest possibilities of data verification, fast, deep and even paranoid-level, with support for multithread acceleration on SSD/NVMe (real world 1GB/s+). Freeware Win GUI (PAKKA) here https://www.francocorbelli.it/pakka/build/latest No complex repository folders, just one file. Latest "hashers" (SHA-3, BLAKE3 w/HW acceleration on Win, XXH3) 15+ years of developing (2009-now). Seeing is believing! https://github.com/fcorbelli/zpaqfranz/wiki

m23 is a free software distribution system (license: GPL), that installs (via network, starting with partitioning and formatting) and administrates (updates, adds / removes software, adds / removes scripts) clients with Debian, (X/K)Ubuntu and LinuxMint. It is used for deployment of Linux clients in schools, institutions and enterprises. The m23 server is controlled via a web interface. A new m23 client can be installed easily in only three steps. Group functions and mass installation tools make managing a vast number of clients comfortable. The integration of existing clients (with .deb-based distributions) into the system is possible, too. Client backup and server backup are included to avoid data loss. With the integrated virtualisation software, m23 can create and manage virtual m23 clients, that run on real m23 clients or the m23 server. Scripts and software packages (for installation on clients) can be created directly from the m23 web interface.

This is intended to be a program for Linux, Mac OS X and Windows using the QT API, to manage and transfer from the computer to the PSP homebrew binary files, savegame backups, video and audio files.

A slightly reduced strength bulk encryption. In exchange for the reduced strength, you get the ability to rsync the encrypted files, so that local changes in the plaintext file will result in (relatively) local changes to the cyphertext file.
