Free recovery software for linux

PING is a live Linux ISO, based on the excellent RIP (Recovery Is Possible) distribution. PING can be burnt on a CD and booted, or integrated in a PXE / RIS environment.
Several tools have been added and written, so to make this ISO the perfect choice to backup and restore whole partitions, an easy way. It sounds like Symantec Ghost(tm), but has even better features, and is totally free.
Main features:
- Backup and Restore partitions or files to a MS Network Shared directory;
- Backup and Restore the BIOS data as well;
- Either burn a bootable CD / DVD, either integrate within a PXE / RIS environment;
- Possibility to Blank local admins password;
- Create your own restoration bootable DVD (see the Howto Documentation);
- Partition and Format a disk before installing Windows (so to make sure your unattended Windows installation will happen on the right partition);
Specific advantages Linux brings you over DOS and Ghost :
- Most network cards automatically recognized by the Kernel (unlike DOS);
- Most CD/DVD readers automatically recognized by the Kernel (unlike DOS);
- You dont have to run a Ghostcast server to receive images over the network.
Whats New in 2.00 RC7 Development Release:
- NTFS filesystems were not being resized to the maximum size that the partition could contain, though logging reported such.
- An occasional hang on some systems when it came to mount NTFS partitions was fixed.
- For an unknown reason, using NTFS-3G drivers rather than native kernel drivers seems to resolve the issue.
- The kernel was updated to Linux 2.6.22.4.
- Some more network and S-ATA/SCSI drivers have been compiled.

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.
