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.
LBackup is a simple backup system aimed at systems administrators who require reliable backups with minimum fuss. It is configured with configuration files, and the backup is started from the command line. It has been tested for over 10 years. Backups can be to local media, or to remote media via one or more networks. The networks may be private LANs, WANs, or sets of untrusted public networks such as the Internet.
Beaver is a simple concurrent backup system with snapshotting. It is based on a simple list of servers, a file of configuration options, and lists of things to be excluded or included. More powerful configuration options are available in the configuration files. Different copies of beaver backup can be run on the same server with different configuration files. Beaver backup is normally run by cron on a central backup box and uses keychain for remote authentication.
Backupninja allows you to coordinate system backup by dropping a few simple configuration files into /etc/backup.d/. Most programs you might use for making backups don't have their own configuration file format. Backupninja provides a centralized way to configure and schedule many different backup utilities.
CryptBackup is an encrypted backup application for Linux desktop users. It allows even a layperson to backup their home directory (including the desktop) on an encrypted external device with just a few clicks. Even the setup is only to choose the external device (such as an external hard drive) and to set a password.
Tartarus is a backup script designed to make backups of dedicated servers easy. It employs a range of standard Unix tools to achieve this goal, to simplify disaster recovery even when only a minimal rescue system is available. Archives can be stored on-the-fly on FTP servers as well as in the local filesystem, while a plugin system allows adaption to a wide range of usage scenarios. The use of LVM snapshots and the creation of differential backups are also included, as is an expire script to remove older archives from an FTP site.
RBME (Rsync Backup Made Easy) is a simple tool to assist in implementing a general backup solution based on rsync and hardlinks with an automated management of the disk space on the backup media. This is achieved by removing old backups from the backup media in a way which will ensure that (over the long run) the amount of backups should even out for all hosts involved. After the initial full backup RBME will forever do incremental backups against the last backup to conserve time and network bandwidth.
