Back In Time is a comfortable and well-configurable graphical frontend for
incremental backups using rsync, with a
command-line version also available. Modified files are transferred, while
unchanged files are linked to the new directory using rsync's hard link feature,
saving storage space. Restoring is straightforward via file manager, command
line or Back In Time itself.
It is written in Python3 and available for all major GNU/Linux distributions
as command line tool backintime and GUI backintime-qt. Backups can be
scheduled and stored locally or remotely through SSH.
More background info in CONTRIBUTING and HISTORY.
The project is in active development since the current team joined in summer 2022, continuing the work of the previous maintainer, Germar. Development is done voluntarily in spare time so things need to be prioritized. Stick with us, we all ♥️ Back In Time.
Current focus is on fixing major issues instead of implementing new features. Stabilize the code base and its test suite is also a matter. Read the strategy outline for details. Please see CONTRIBUTING if you are interested in the development and have a look on open issues especially those labeled as good first issues and help wanted.
Since around 2024, @buhtz, part of the projects third generation of maintainers, has been the sole maintainer. He handles all core tasks, from code analysis and documentation to issue resolution and feature implementation. The work is carried out voluntarily during spare time. The project continues to benefit from an active and engaged community that provides advice, expertise, and contributions, ensuring it thrives and evolves.
The project was reactivated in 2022 and thanks in large part to Michael Büker (@emtiu) and Jürgen (@aryoda), who helped relaunch and shape its direction. See HISTORY for more details.
Back In Time is included in
many GNU/Linux distributions.

-rw-r--r-- in the backup target.rsync is executed with --perms option
which tells rsync to preserve the source file permission.Therefore backups can be larger and slower, especially the first backup after upgrading to a version >= 1.2.0.
If you don't like the new behavior, you can use Expert Options ->
Paste additional options to rsync to add --no-perms --no-group --no-owner
to it. Note that the exact file permissions can still be found in
fileinfo.bz2 and are also considered when restoring files.
See CONTRIBUTING file for an overview about the project's workflow and strategy.
