SystemImager automates the installation of Linux to masses of similar machines. Software distribution, configuration, and operating system updates are made easy, including updates from one Linux release to another. It can also be used for content distribution on Web servers. It is most useful in environments with large numbers of identical machines. Some typical environments include Internet server farms, high performance clusters, computer labs, and corporate desktop environments where all workstations have the same basic hardware configuration.
VDMFEC implements Block ECC using a Forward Error Correction (FEC) code based on Vandermonde (VDM) matrices in GF(2^8) due to Luigi Rizzo. Given the FEC parameters K and N, with N greater than K, N blocks are written for every K input blocks in such a way that any K blocks are sufficient to reconstruct the data. That is, up to N - K blocks out of every group of N blocks may be lost without loss of data. VDMFEC's primary application is intended to be in recovering data from unreliable media such as diskettes. With appropriate parameters, files may be recovered even with many read errors. (Note that you must write the data to the diskette using this program in order to be able to recover the data later!)
fsbackup is an incremental backup creation utility. It supports backup compression and encryption. Backups can be stored on the local file system, and a remote host (via SSH, or FTP). Some additional scripts allow backup SQL tables from PostgreSQL and MySQL, save system configuration files, and a list of installed packages. Backed-up files can be recovered, and system packages can be reinstalled.
flexbackup is a configurable and easy to use Perl-based backup tool, that can backup local files as well as remote machines (using ssh). It allows the backup itself to be made with afio, cpio, tar, dump, star, or pax. It can work with tape drives, on-disk archive files, or on-disk directory trees.
Storix Backup Administrator (SBAdmin) provides both an intuitive graphical user interface and command line options for performing backups of a standalone system, or managing backups of all Linux and AIX systems on a network. In addition to backing up data onto a network server, tape, or disk device, it can reinstall a complete system from scratch, clone or migrate systems, manage volumes and RAID devices, and restore data in any configuration you choose. It features easily accessible documentation.
The Linbox Rescue Server (LRS) is a tool to centralize hard disk images (like Ghost Enterprise Server), file backups, hardware and software inventory (with Windows, Linux, and Mac OS X agents), secure software deployment using OpenSSH, and remote access on a single server. It can be managed from any PC through a Web-based administration interface, and disk images can be restored using PXE boot or using a bootable CD or DVD. It supports Ext2/3, ReiserFS, XFS, JFS, and LVM v1/v2.
