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.
The Zumastor Linux storage project adds enterprise storage features to Linux, primarily improved snapshots and remote replication. Point-in-time, near zero-cost, block level snapshots can be added to any existing filesystem and performance does not degrade with multiple snapshots. Remote replication is achieved by sending minimal block level deltas between snapshots without having to traverse the entire filesystem like rsync does.
NNNbackup (No-name network backup) is a simple backup system framework for data in an SMB/CIFS networked environment. It can also be used for backing up local data. The primary focus of this system is the simple selection of data to be backed up and the security of said data. It is also very portable because it relies on common Linux tools and its behavior is controlled entirely by a single and simple configuration file.
Backup-DVD is a simple script to backup the entire system on a rewritable DVD. It is designed to be manily used as a cron job. It logs operations in /var/log/backup.log and sends feedback by email, and it is fully configurable by editing /etc/backup-dvd/backup-dvd.conf. This script cannot be run as sudo; it must be run directly as root.
bak2disc is a disc-based backup script aimed at being easy to use and powerful. Its most notable feature is the way it groups common files and directories together to preserve structure when data is divided into discs. This functionality is a tunable threshold that lets you control the balance between data contiguity and maximum disc usage. In addition, bak2disc also features resume support, which allows you to stop burning between discs and continue later. Burning is done on-the-fly, using growisofs for DVDs and cdrecord for CDs.
