pkt is a universal XML packet archiver. It can manipulate files for backing up documents, transferring them across networks, emailing them, and sharing them by other means (p2p etc). It uses plugin filters to do the job and handles virtually any format available if there is a plugin for it. It handles encryption, compression, conversion, parity checking, decryption, decoding, repairing, rebuilding, and other tasks using a universal file format (XML-based). By default, all pkt output is in 7-bit ASCII which is UTF encoded and is compatible with XML parsers. pkt files can be disassembled, reassembled, and repaired by hand if necessary. pkt also supports the use of 8-bit compressed XML packets for its archives using one of several compression algorithms. In general, pkt will try to use the best algorithms available.
bytecounter is a program that copies data while showing a status line indicating the data rate and estimated time remaining. Optionally, it retries on errors, which is useful for recovering files from bad media. It designed to be used "in-between" two programs to measure rate of data flow, such as between the output of a tar command and a file. It works with files, floppy disks, hard disks, terminals, tapes, CD-ROMs, FIFOs, and anything else you can think of.
FindFile will be a collection of tools for recovering files from filesystems with corrupted directories, allocation tables, etc. This can be useful when the partition table (or more) of a hard disk is corrupted, or when you have a memory card of a digital camera which is corrupted. For now, only a tool for recovering JPEG files is included.
Magic Rescue scans a block device for file types it knows how to recover and calls an external program to extract them. It looks at "magic bytes" in file contents, so it can be used both as an undelete utility and for recovering a corrupted drive or partition. It works on any file system, but on very fragmented file systems it can only recover the first chunk of each file. These chunks are sometimes as big as 50MB, however.
G4L is a hard disk and partition imaging and cloning tool. The created images are optionally compressed, and they can be stored on a local hard drive or transferred to an anonymous FTP server. A drive can be cloned using the "Click'n'Clone" function. G4L supports file splitting if the local filesystem does not support writing files larger than 2GB. The included kernel supports ATA, serial-ATA, and SCSI drives. Common network cards are supported. It is packaged as a bootable CD image with an ncurses GUI for easy use.
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_rescue copies data from one file or block device to another. It is intended for error recovery, so by default, it doesn't abort on errors and doesn't truncate the output file. It uses large block sizes to quicken the copying, but falls back to small blocks upon encountering errors. It produces reports that allow you to keep track of bad blocks. dd_rescue features a number of optimizations, such as sparse block detection, preallocation, and Linux zerocopy (splice). It supports data protection by (multi-pass) overwriting of files or partitions with good and fast random numbers.
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.
