Kopia
Cross-platform backup tool for Windows, macOS and Linux
...Instead of imaging entire machines, it focuses on backing up selected files and directories with efficient incremental backups that only transfer changed data, which reduces storage and bandwidth needs. Kopia has both a command-line interface for automation and scripting as well as a graphical UI for interactive use, making it suitable for advanced users and those who prefer visual tools. Its architecture supports end-to-end encryption, optional compression, and deduplication, so multiple backups can share data efficiently, and repositories can be stored securely even in untrusted locations.
