Free linux data recovery software for linux

Kaboot Linux Operating system aims to provide an operating system which you can take anywhere and has all your favourite programs on.
Kaboot operating system is avaliable as a Live CD or Live USB you can take with you anywhere.
A number of different versions are avaliable, two optimised for size or speed, one for functionality, and one science based.
All containing a host of useful programs able to boot virtually any computer (meeting the minimum requirements) from CD and
USB.Kaboot is still in active development and if you find a bug or fix, you can let me know in the forums.
Enhancements:
- A network bug was fixed.
- A few debugging utilities were added.
- Hotplugging was implemented.

Linux Commander is a powerful file manager for the X Window System.

It is partially modelled after Window Commander for Windows.

Make CD-ROM Recovery makes a bootable (El Torito) disaster recovery image (CDrec.iso), including backups of the linux system to the same CD-ROM (or CD-RW) if space permits, or to a multi-volume CD-ROM set. Otherwise, the backups can be stored on another local disk, NFS disk or (remote) tape.

After a disaster (disk crash or system intrusion) the system can be booted from the CD-ROM and one can restore the complete system as it was (at the time mkCDrec was run) with the command /etc/recovery/start-restore.sh

Disk cloning (clone-dsk.sh script) allows one to restore a disk to another disk (the destination disk does not have to be of the same size as it calculates the partition layout itself). A thrid script, restore-fs.sh, will restore only one filesystem to a partition of your choice, and the user can choose with which filesystem the partition has to be formatted.

Linux 2.2.x, 2.4.x and 2.6.x kernels are supported, and if size of the kernel is not too big a boot floppy can be made, otherwise a 2.88 Mb boot floppy will be emulated on CD-ROM.

MkCDrec supports ext2 , ext3, minix, xfs , jfs, reiserfs file systems, LVM and software RAID (multiple devices). Each file system is backed up as a compressed tar archive (including the tar log). The compress program used is the users choice (compress, gzip, bzip2, lzop,...)

But there is more: msdos, fat, vfat and ntfs mounted partitions are recognized and are saved as compressed dumps (on CD, tape, etc.)
The user has the possibility to encrypt all backups with openssl if desired (see the Config.sh configuration file for more information).

To restore your system completely just boot from the first CD-ROM made by mkCDrec and type "/etc/recovery/start-restore.sh " to restore everything from CD. Automatic Disaster Recovery and One Button Disaster Recovery are supported by mkCDrec too.
With the clone-dsk.sh script one can restore selective a disk or partitions to another free disk.

mkCDrec supports IDE (inclusive ATA), SCSI disks, hardware RAID based disks (e.g. Compaq SMART2 Disk Array), LVM and software RAID. With an El-Torito CD-ROM you can boot from an IDE or SCSI based CD-ROM drive on IA32/64, powermac and x86_64 GNU/Linux based computer systems only.

Common Data Format is a self-describing data abstraction for the storage and manipulation of multidimensional data in a platform- and discipline-independent fashion.
It consists of a scientific data management package (known as the "CDF Library") that allows programmers and application developers to manage and manipulate scalar, vector, and multi-dimensional data arrays.
Enhancements:
- Adds new sets of APIs to allow Standard Interface to interact with zVariables and other CDF-related information.
- Adds MingW and FreeBSD ports.
- Adds support for Intel C++ and Fortran for Linux.
- Adds the ability to create legacy CDF 2.7 files.
- Fixes a bug that prevented directories from having .cdf or .skt extensions.

Linux Mobile System project (LMS) is a full Linux system whose support is the new USB Flash Memory Drives. The intention is to boot any PC with USB support with our system and therefore we will have every administration and analysis applications that we have selected, so we will not need install it. This way, always we will be able to get our Linux system ready to use in our pocket.
This project arose with the intention to study the Linux system of exhaustive way and simultaneously enjoy with it. The initial idea is to fuse two separated disciplines: the programming and the systems management. So well center our study in the denominated "system programming, as much networking level as at device level (drivers).
Main features:
- To initiate our Linux system from memories flash USB.
- The system will be a selection of common GNU tools in every system: disk diagnosis, memory, hardware, networks monitoring tools, etc.
- LMS Tux
- As far as possible well develop new tools and/or utilities with the objective to study deeply the underlying technology.
- The programming languages used will be C, C++, Python and Perl, without forget the system shell scripts.
- The resources minimization (disk space, memory...) isnt a functional objective of the developments.
LMSs main aim is to achieve a highly specialized distribution of GNU/Linux which can carried through the USB Flash Memory Drives. Once the distribution is ready in the USB device, it can be carried in your own pocket and you can start up any PC x86 with no need to install it directly in the PC.
The LMS system is aimed at the development of specific tasks such as network administration, security analysis of networks, and recovery and repair of host data, as well as all information exchange, which is what makes it different from other portable systems such as "live CDs". The main idea is to carry all the potency of Linux and our tools in our own pockets, ready to be used.

GNU ddrescue is a data recovery tool. GNU ddrescue copies data from one file or block device (cdrom, hard disc, etc) to another, trying hard to rescue data in case of read errors.
Ddrescue does not truncate the output file if not asked to. So, every time you run it on the same output file, it tries to fill in the gaps.
The basic operation of ddrescue is fully automatic. That is, you dont have to wait for an error, stop the program, read the log, run it in reverse mode, etc.
If you use the logfile feature of ddrescue, the data is rescued very efficiently (only the needed blocks are read). Also you can interrupt the rescue at any time and resume it later at the same point.
Automatic merging of backups: If you have two or more damaged copies of a file, cdrom, etc, and run ddrescue on all of them, one at a time, with the same output file, you will probably obtain a complete and error-free file.
This is so because the probability of having damaged areas at the same places on different input files is very low. Using the logfile, only the needed blocks are read from the second and successive copies.
The logfile is periodically saved to disc. So in case of a crash you can resume the rescue with little recopying.
Also, the same logfile can be used for multiple commands that copy different areas of the file, and for multiple recovery attempts over different subsets.
Ddrescue aligns its I/O buffer to the sector size so that it can be used to read from raw devices. For efficiency reasons, also aligns it to the memory page size if page size is a multiple of sector size.
Whats New in 1.5 Stable Release:
- The license has been updated to GPL version 3 or later.
Whats New in 1.6-pre2 Development Release:
- Support for sparse writes to the output file has been added.
