SystemRescueCd is a Linux system on a bootable CD-ROM for repairing your system and recovering your data after a crash. It aims to provide an easy way to carry out admin tasks on your computer, such as creating and editing the partitions of the hard disk. It contains lots of system utilities (GParted, parted, partimage, Sfdisk, fstools, …[details below]) and basic tools (editors, file managers like midnight commander, network tools … [details below]). It is very easy to use: just boot the CDROM. The kernel supports most of the important file systems (ext2/ext3, reiserfs, reiser4, xfs, jfs, vfat, ntfs, iso9660), as well as network filesystems (samba and nfs).

Partimage is a Linux utility which saves partitions having a supported filesystems (see below) to an image file. It is a free and open source alternative to the popular software Norton Ghost or DriveImage. Most Linux and Windows filesystems are supported. The partition image file can be compressed with the gzip / bzip2 programs to save disk space, and can be split into multiple files to easily copy them on CDs / DVDs. Partitions can also be saved across the network using the partimage network support, or using Samba / NFS. If you don't want to install Partimage or you don't have a running Linux installation then you can download and burn SystemRescue CD. It is a live cd, like Bart's Rescue CD, that allows to use Partimage immediately even if your computer has no operating system installed (useful to restore an image), and it also allows to save an image on a DVD on the fly.

Mempile from Israel has developed a removable optical storage technology allowing for the storage of 1 Terabyte (1,000 Gigabytes) of information on a single inexpensive disc. The device builds on the existing know-how attained through the development of CDs and DVDs, extending it so as to write layers upon layers of stacked information. This quantum leap in storage capacity (viz., equivalent to 200 DVDs on a single disc) will allow it to offer a unique and exceptional solution for the personal video recording, high-resolution TV, and archiving markets. The product itself will look and behave very much like the familiar removable optical devices; the disc itself is 12cm in diameter and made out of an inexpensive translucent polymer.
