HTTrack is an easy-to-use offline browser utility. It allows you to download a Web site from the Internet to a local directory, building recursively all directories, getting HTML, images, and other files from the server to your computer. HTTrack arranges the original site's relative link-structure. Simply open a page of the mirrored Web site in your browser, and you can browse the site from link to link, as if you were viewing it online. HTTrack can also update an existing mirrored site, and resume interrupted downloads. WebHTTrack is a Web-based GUI for HTTrack.
Loki Setup is a graphical installer for Unix applications. It features descriptions of the package to install in XML, a GTK interface that can be dynamically redefined by the user with Glade, raw and ncurses console interfaces, and the automatic generation of uninstall scripts. It has been successfully used on many Linux and UNIX platforms. It includes tools for uninstalling, patching, and recovering installations. It operates independently from any package managers.
fsbackup is an incremental backup creation utility. It supports backup compression and encryption. Backups can be stored on the local file system, and a remote host (via SSH, or FTP). Some additional scripts allow backup SQL tables from PostgreSQL and MySQL, save system configuration files, and a list of installed packages. Backed-up files can be recovered, and system packages can be reinstalled.
dnbackup is yet another client-server backup solution. Design goals include portability (within Unix variants), security, minimizing trust between client and server, ability to optimize for remote backups over slower speed links, and OS independence in the communication protocol (thus allowing for non-UNIX clients).
