LVM

The Logical Volume Manager (LVM) is a subsystem for online disk storage management which has become a de facto standard for storage management under Linux.

ZFS

ZFS is a new kind of file system that provides simple administration, transactional semantics, end-to-end data integrity, and immense scalability. ZFS is not an incremental improvement to existing technology; it is a fundamentally new approach to data management. We've blown away 20 years of ... [More] obsolete assumptions, eliminated complexity at the source, and created a storage system that's actually a pleasure to use. [Less]

rdiff-backup

rdiff-backup backs up one directory to another, possible over a network. The target directory ends up a copy of the source directory, but extra reverse diffs are stored in a special subdirectory of that target directory, so you can still recover files lost some time ago. The idea is to combine the ... [More] best features of a mirror and an incremental backup. rdiff-backup also preserves subdirectories, hard links, dev files, permissions, uid/gid ownership (if it is running as root), modification times, acls, eas, resource forks, etc. Finally, rdiff-backup can operate in a bandwidth efficient manner over a pipe, like rsync. Thus you can use rdiff-backup and ssh to securely back a hard drive up to a remote location, and only the differences will be transmitted. [Less]

rsnapshot

rsnapshot is a filesystem snapshot utility for making backups of local and remote systems. Using rsync and hard links, it is possible to keep multiple, full backups instantly available. The disk space required is just a little more than the space of one full backup, plus incrementals. ... [More] Depending on your configuration, it is quite possible to set up in just a few minutes. Files can be restored by the users who own them, without the root user getting involved. There are no tapes to change, so once it's set up, you may never need to think about it again. rsnapshot is written entirely in Perl. It should work on any reasonably modern UNIX compatible OS, including: Debian, Redhat, Fedora, SuSE, Gentoo, Slackware, FreeBSD, OpenBSD, NetBSD, Solaris, Mac OS X, and even IRIX. [Less]

btrfs

Btrfs kernelspace. Btrfs is a new copy on write filesystem for Linux aimed at implementing advanced features while focusing on fault tolerance, repair and easy administration. Initially developed by Oracle, Btrfs is licensed under the GPL and open for contribution from anyone. Linux has a ... [More] wealth of filesystems to choose from, but we are facing a number of challenges with scaling to the large storage subsystems that are becoming common in today's data centers. Filesystems need to scale in their ability to address and manage large storage, and also in their ability to detect, repair and tolerate errors in the data stored on disk. Btrfs is under heavy development, and is not suitable for any uses other than benchmarking and review. The Btrfs disk format is not yet finalized. [Less]

NILFS

A New Implementation of the Log-structured File System for Linux

flyback-ng

An easy to use backup system based on Derek Andersons project Flyback. http://flyback-project.org/ New Features i plan to finsih some of the features that started to appear in the origrnal project as well as introduce some of my own. My Main task at the moment is to remove the Gconf ... [More] dependancies to allow for automatic cron based backups. I also plan to split the User interface and create a command line version that can be used on many more systems Version 5 on a pc near you soon i have currently removed the gconf depends within the code so that automatic back is now possible. i will release a package for this shortly just working on the last few details.

Mound Data Manager

Mound Data Manager is a tool that can manage data in the context of other applications. You can take snapshots, delete, and move data from many of your favorite applications.

faces

faces is a powerful and free project management tool. faces stands for flexible, automated, calculating, extensible, simulating. It is based on python, an easy to learn and powerful programming language. See also https://launchpad.net/faces2 for an attempt to "reboot" the project's development.

smarbs

smarbs is a simple backup script written in ruby. Using rsync it creates full snapshots in certain intervals within a minimal use of space. smarbs is easy configurable via config files and can be run as a cronjob.
