Clonezilla is a partition or disk cloning tool similar to Symantec Ghost. It saves and restores only blocks in use on the hard drive if the file system is supported. For unsupported file systems, dd is used instead. It has been used to clone a 5 GB system to 40 clients in about 10 minutes.
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.
SafeKeep is a centralized and easy to use backup application that combines the best features of a mirror and an incremental backup. It enhances the power of rdiff-backup with simple, centralized configuration, while adding support for LVM snapshots, database dumps, and convenient SSH key management.
glucopy-glurestore is a set of scripts for copying and restoring a fully functional GNU/Linux (or other Unix-like) system. The glucopy script will back up all system content (system and user files), while the glurestore script will partition and format an identical system, restore the system and user files, and make the system bootable. The scripts are included in the HTML documentation.
Partimage Is Not Ghost (PING) is a live Linux ISO based on LFS (Linux From Scratch). It can be burnt on a CD and booted, or integrated in a PXE/RIS environment. Several tools that make it the perfect choice for easily backing up and restoring whole partitions are included. It supports backups to and from SMB shares, backup of BIOS data, the ability to blank the local admin's password, creation of bootable restoration DVDs, the ability to partition and format a disk before installing Windows, and more.
imapsync is a tool for facilitating incremental recursive IMAP transfers from one mailbox to another. It is useful for mailbox migration or backup, and reduces the amount of data transferred by only copying messages that are not present on both servers. Read, unread, and deleted flags are preserved, and the process can be stopped and resumed. The original messages can optionally be deleted after a successful transfer.
RVM is an archive manager that uses rsync to manage backups of multiple clients across multiple logical partitions (vaults). It has some features that some other rsync-based backup schemes lack, such as being written in C++, needing no scripts or other programs than rsync and any binaries on which rsync depends (such as SSH), the ability to manage multiple instances of rsync connections to separate clients in parallel, the ability to use multiple logical partitions (vaults) in a configurable fashion for purporses of redundancy and added reliability, and the use of hard links for files that have not changed from one archive to the next.
