Linux Lite 4.0 Suggestions welcomed

File backup is a habit everyone should practice! I use FreeFileSync to backup files to an external drive. It's pretty easy to figure out, and has lots of options. I choose which directories to backup, and it's smart about updating just the files that have changed or are new. (I think it's a different use case from what Systembak does.)

I also install it on machines of any Linux newbie as it's also available on Windows. Meaning, usually I have advised users while still using Windows to use for the most important system task (backup) FreeFileSync. Therefore they are already familiar with it.
I have chosen it once as it was not only available for Linux and Windows, but even as portable app for Windows, so that it could be used without admin rights (no installation required). Unfortunately the portable feature is meanwhile only available in the paid version. Therefore I'm keeping my eye open for an alternative.
