osarchiver (Operating System Archiver) creates CD/DVD backup images, useful for operating system disaster recovery. It features compact size, utilization of already-present operating system functionality, multiple Red Hat version compatibility, multi-volume capability, parallel compression, and hardware flexibility.
The RegLookup project is devoted to direct analysis of Windows NT-based registry files. RegLookup provides command line tools, a C API, and a Python module for accessing registry data structures. The project has a focus on providing tools for digital forensic examiners (though it is useful for many purposes), and includes algorithms for retrieving deleted data structures from registry hives.
rfs is a shell script for creating and updating a local spare system disk. The main goal is to recover a working system after a crash quickly. In this case, "quickly" means the time it takes to reboot the machine. rfs stands for "replication of filesystems". Like rsyncbackup, rfs is built on top of rsync.
MBCD (MultiBootCD) is a shell script to make a customized CD-ROM that can boot any kind and any number of image files. Currently, 4 types of images are supported: floppy images (1.2M, 1.44M, or 2.88M), Knoppix-like images, kernel-binary images (e.g. memtest86), and the Windows XP Recovery Console.
dd_rhelp allows users to retrieve, quickly and easily, recoverable data from any device with bad sectors. It will copy it using dd_rescue in all the appropriate ways (reverse copy, setting start and stop offset accordingly to previously rescued data) to recover the maximum data possible before spending time on bad sectors. It is straightforward to use, supports ctrl-c at anytime, can resume a job (or standalone dd_rescue job) by parsing the dd_rescue logs, and displays a nice ASCII bar showing rescue progress.
