Kopia

Kopia is a fast and secure open-source backup and restore tool. It creates encrypted snapshots of the files and folders you choose and saves them to remote or cloud storage, a network-attached storage or server, or your own machine.

It helps both advanced and regular users keep important data safe, with command line and graphical versions. Kopia does not image your whole machine. Instead you pick the files and directories to back up.
