Having backups of important data is a necessary measure to take, since human and machine processing errors are very likely to generate corruption as time passes, and also the physical media where the data is stored is inevitably destined to fail. This page introduces many applications available for the task, subdivided in categories to best suit most use cases.

Overview

Before you start trying various programs out, try to think about your needs, e.g. consider the following questions:

  • What backup medium do I have available? (CD, DVD, remote server, external hard drive, etc.)
  • How often do I plan to backup? (daily, weekly, monthly, etc.)
  • What features do I expect from the backup solution? (compression, encryption, handles renames, etc.)
  • How do I plan to restore backups if needed?

Data synchronization

These applications simply keep directories synchronized between multiple locations/machines, in a "mirror" fashion. Nonetheless, most of them still allow storing and reverting to old revisions of modified or deleted files.

See also Wikipedia:Comparison of file synchronization software.

  • BitTorrent Sync — File sharing system that relies on the BitTorrent protocol.
https://www.getsync.com/ || btsyncAUR
  • Free File Sync — Free File Sync helps you synchronize files and synchronize folders for Windows, Linux and Mac OS X. It is designed to save your time setting up and running backup jobs while having nice visual feedback along the way.
http://freefilesync.sourceforge.net/ || freefilesyncAUR
  • git-annex — Creates a synchronised folder on each of your OSX and Linux computers, Android devices, removable drives, NAS appliances, and cloud services.
http://git-annex.branchable.com/ || git-annex
  • Grsync — GTK+ interface to rsync
http://www.opbyte.it/grsync/ || grsync
  • osync.sh — Osync is a robust bidirectional file synchronization tool written in bash and based on rsync. It works on local and / or remote directories via ssh tunnels. It's mainly targeted to be launched as cron task, with features turned towards automation among:
    • Execution time control
    • Fault tolerance with possibility to resume on error
    • Soft deletion, on-conflict backups with automatic cleanup
    • Alert notifications via email
    • Before and /or after time controlled local and / or remote command execution
    • File monitor mode
http://www.netpower.fr/osync || not packaged? search in AUR
  • rsync — A file transfer program to keep remote files in sync.
    • rsync almost always makes a mirror of the source.
    • It is possible to restore a full backup before the most recent backup if hardlinks are allowed in the backup file system. See Back up your data with rsync for more information.
    • If hard links are not allowed, it is impossible to restore a full backup before the most recent backup (but you can use --backup to keep old versions of the files).
    • Standard install on all distros.
    • Can run over SSH (port 22) or native rsync protocol (port 873).
    • Win32 version available.
http://rsync.samba.org/ || rsync
  • SparkleShare — Collaboration and sharing tool based on git written in C Sharp.
http://sparkleshare.org/ || sparkleshare
  • Syncthing — Open-source file synchronization client/server application, written in Go, implementing its own, equally free Block Exchange Protocol.
https://syncthing.net/ || syncthing syncthing-gtk
  • Synkron — A folder synchronization tool.
    • Syncs multiple folders.
    • Can exclude files from sync based on wildcards.
    • Restores files.
    • Cross-platform support.
http://synkron.sourceforge.net/ || synkronAUR
  • Unison — A program that synchronizes files between two machines over network (LAN or Inet) using a smart diff method + rsync. Allows the user to interactively choose which changes to push, pull, or merge.
http://www.cis.upenn.edu/~bcpierce/unison/ || unison

Incremental backups

Applications that can do incremental backups remember and take into account what data has been backed up during the last run (so-called "diffs") and eliminate the need to have duplicates of unchanged data. Restoring the data to a certain point in time would require locating the last full backup and all the incremental backups from then to the moment when it is supposed to be restored. This sort of backup is useful for those who do it very often.

Some do not apply compression or encryption: on one hand, a working copy of everything is immediately available, no decompression/decryption needed; a downside to rsync-type programs is that they cannot be easily burned and restored from a CD or DVD.

Others tend to create (big) archive files and (of course) keep track of what has been archived: creating .tar.bz2 or .tar.gz archives has the advantage that you can extract the backups with just tar/bzip2/gzip, so you do not need to have the backup program around.

See also Dotfiles#Version control.

Legend:

  • Name: the application name, linking to the official website.
  • Installation: a link to the main ArchWiki article, if existing, or directly to the package pages.
  • Implementation: the programming language, library, or utility that the application is based on.
  • Compressed storage: compression is used for storage.
  • Encrypted storage: encryption is used for storage.
  • Delta transfer: only the modified parts of files are transferred.
  • Encrypted transfer: data is encrypted by default when transferred over a network.
  • FS metadata: file system permissions and attributes are backed up.
  • Easy access: the backup is stored plainly in the file system, or is mountable as such.
  • Resumable: the backup can be resumed without restarting it if interrupted.
  • Handles renames: moved/renamed files are detected and not stored or transferred twice; it typically means that a checksum is computed for files or chunks thereof.
  • CLI: the application is command-line driven, i.e. it is scriptable.
  • Other interfaces: the application has the specified user interfaces, e.g. GUI, TUI, or web-based.
  • Increment type: the strategy used to reduce used space by deduplicating data (i.e., besides compression).
    • file-based: if a file is modified, the entire new version is stored at each snapshot.
      • hard-links: unmodified files are stored as hard links to previous versions.
    • chunk-based: only the modified parts of files are stored at each snapshot.
  • Licence: the licence of the server and client applications.
  • Other platforms: supported operating systems other than Linux.
  • Active: whether the project is currently maintained.
  • Specificity: brief notes about special features that notably set the application apart from the others.

Single machine

These applications are aimed at backing up data from the machine they are installed on, although the backup destination can be located on an external machine or storage media.
