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.
Areca is a file backup system that supports data compression (zip / zip64 format) and encryption, incremental backups, FTP/SFTP file transfer, delta storage mode, and many other features. It includes a transaction mechanism, which guarantees the integrity of your backups. Two user interfaces are available: a command-line interface (useful for backup automation) and a graphical user interface (useful for backup administration).
DiskSearch is a tool for searching for files on all your removable media disks, including CDs, ZIP disks, and backup tapes. It allows you to search for songs on your MP3 CDs or for a document on your backup DVDs. For advanced queries, a regular expression search mode is provided. Searches are based on a simple database file, which needs to be filled once by adding all your disks to it.
PHP Backup Maker (PDM) is a smart PHP backup solution. The script reads a given source directory (with its subdirectories) and then creates a set of directories filled with the content of the source directory, arranged in groups to fit a given capacity. It can be used to create CD sets for backups. It also supports ISO image creation, direct CD and DVD burning via cdrecord/growisofs, backup of files bigger than media capacity (splitting), automatic file index creation, and more.
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.
mylvmbackup is a Perl script for quickly creating backups of a MySQL server's data files. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, makes an LVM snapshot of the volume containing the MySQL data directory, and unlocks the tables again. The snapshot process takes only a small amount of time. When it is done, the server can continue normal operations while the actual file backup proceeds. The actual backup can be performed by using tar, rsync, or rsnap.
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.
Finnix is a small, self-contained, bootable Linux CD distribution ("LiveCD") for system administrators, based on Debian testing. You can use it to mount and manipulate hard drives and partitions, monitor networks, rebuild boot records, install other operating systems, and much more.
Bacula is a set of programs that allow you to manage the backup, recovery, and verification of computer data across a network of different computers. It is based on a client/server architecture and is efficient and relatively easy to use, while offering many advanced storage management features that make it easy to find and recover lost or damaged files.
Mondo Rescue archives Linux and Linux/Windows systems to tapes, CDs, DVDs, USB devices, or ISO images that may be used to restore some or all of your OS and data in the event of catastrophic data loss, or for cloning a system. The emphasis is on stability and ease of use. Currently, ext2, ext3, ext4, (v)fat, minix, ReiserFS, XFS, and JFS filesystems are supported, as are RAID, DM, Multipath, and LVM.
