- bit-team/backintime: A comfortable and well-configurable graphical Frontend for incremental backups, with a command-line version also available. (github.com)
- Modified files are transferred, while unchanged files are linked to the new folder using rsync's hard link feature, saving storage space. Restoring is straightforward via file manager, command line or Back In Time itself.
- BorgBackup – Deduplicating archiver with compression and authenticated encryption (www.borgbackup.org)
- deduplicating archiver — est. 2015

- restic · Backups done right! (restic.net)
- Syncthing (syncthing.net)
- Syncthing is a continuous file synchronization program. It synchronizes files between two or more computers in real time, safely protected from prying eyes. Your data is your data alone and you deserve to choose where it is stored, whether it is shared with some third party, and how it’s transmitted over the internet.
- git-annex (git-annex.branchable.com)
- git-annex allows managing large files with git, without storing the file contents in git. It can sync, backup, and archive your data, offline and online. Checksums and encryption keep your data safe and secure. Bring the power and distributed nature of git to bear on your large files with git-annex.
- Sync keeps your files safe, secure, and 100% private with end-to-end encryption — not even we can see them. Simple, fast, and always in your control. *unfree* (www.sync.com)
