Simplebackup is a cross-platform backup program. It reads a configuration file, then it builds a compressed file for each of your backup directories or files on your backup list, and places the compressed files into another location. For example, this location can be a network mapped drive in Windows, an NFS mounted drive in Unix, another hard disk, an FTP, SFTP (Secure FTP / SSH2), A HTTP (WebDav) server, or more email accounts, or a tape device (Unix only). This will duplicate your information, doing the so called "backup".
Sitback is a backup daemon/utility for small/medium scale systems. It's easy to setup and maintain but do not expect to setup advanced backup networks with this.
Slony-I is a "master to multiple slaves" replication system with cascading and failover. Slony-I is a system for data centers and backup sites, where the normal mode of operation is that all nodes are available.
Simple Network Backup Utility (Snebu) is a Linux and Unix backup utility that provides many features that are normally found in Enterprise grade backup systems, yet is designed to be simple to install and use.
spantape is a replacement for dd that features the ability to sequentially span a stream of bytes across multiple SCSI tapes. It supports both fixed and variable block sizes and assures the correct order of tapes during data recovery.
splitpipe allows streaming piped output to span multiple volumes, which
might be floppies, cd-recordables, dvd's.
storebackup lets you backup to another disk. Several optimizations for reducing needed disk space and to improve performance. Unifies the advantages of traditional full and incremental backups. It includes tools for analyzing backup data and restoring.
Storix System Backup Administrator
(commercial) Storix System Backup Administrator (SBA) for Linux and AIX provides a user-friendly graphical user interface for complete backup management. SBA also provides the most flexible full system recovery available, supporting various filesystem types, LVM and software RAID, system cloning, and migration onto any hardware configuration. SBA also provides backup encryption and SMB data backup for Windows clients.
Synbak is meant to unify several backup methods in a single application while supplying a powerful reporting system.
Synbak is a wrapper for several existing backup programs suppling to the end user a common method for configuration that will manage the execution logic of any single backup and will make detailed reports of backups result.
Syncsort Backup Express
(commercial) Syncsort Backup Express is an enterprise-level data protection solution that backs up and restores data and applications for a variety of operating systems. It has data protection, disaster recovery and business continuity planning capabilities.
Tapeback is a general purpose tape backup and restore utility set that supports modern SCSI based tape drives. The tapeback utility set also includes a kernel patch (should work on both recent 2.4 and 2.6 Linux kernels) to facilitate real-time tape load status reporting.
Taper is an easy to use backup solution for Linux. It allows backups to tape drives, filesystems, floppy drives, removable devices... In fact, any device that Linux supports. Incremental backup & selective restores are available, as well as backup verifies.
Tardis is a system for making incremental backups of filesystems, much like Apple's TimeMachine, although not quite as polished. It supports encrypted, incremental backups, with filesystem based recovery
tbackup is a general backup system that has both a menu-driven user-friendly interface for interactive use and a flexible command line interface for use in scripts and automatic maintenance. It handles multi-volume archives (even if the volumes have different lengths, and span on partially used cartridges). It can back-up from streams, so that you can tar a group of files, compress them with your favourite program, crypt them and save them to a tape with a single command line, or you can redirect your printouts to the tape.
TkPar is a simple frontend for the command line Parchive programm, written in Perl/Tk. It supports checking, and restoring par sets. To run you need to have perl 5.6, and the perl module Tk installed.
Tape-Oriented Backup is a general driver for making and maintaining backups. Given a set of `volume definitions', it creates arj, tar or afio based backups, and stores them either to a device in /dev, or a file in the filesystem, to be burned to optical media later, moved off to other machines, etc. Through a straightforward configuration file, you can instruct tob to mount and unmount devices before beginning backups.
tresor offers full backup and fast restores for bytepositioning tape drives. This option is available on some Tandberg and Wangtek streamers and some SCSI-2 tape drives.
Uberbackup is a lightweight frontend for GNU tar that supports mt-st. Currently written using REALbasic 5.5.1 using it's Linux binary export feature.
Ukopp is used to copy or back-up disk files to a disk or disk-like device, such as a USB stick. It copies only new or modified files since the last backup, and is therefore quite fast.
Urbackup is a client/server backup system, that through a combination of image and file backup accomplishes both 100% data security and a fast restoration time.
Xfiles is an interactive utility for comparing and merging one file tree with another over a network. It supports freeform work on several machines (no need to keep track of what files are changed on which machine). Xfiles can also be used as a cross-validating disk<->disk backup strategy (portions of a disk may go bad at any time, with no simple indication of which files were affected. Cross-validate against a second disk before backup to make sure you aren't backing up bad data).
yacdbak is intended to facilitate backups to multiple CD-recordables or CD-rewritables on Linux systems. It uses GNU tar and cdrecord.
Yosemite Server Backup
(commercial) Yosemite Server Backup is a complete and affordable data backup and protection solution, enabling you to backup all of your data and restore it quickly in the event of disaster. With broad support for multiple server applications, operating systems, and backup devices, Yosemite Server Backup provides a centralized interface to manage your entire backup strategy.
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.
