Thank you. Your answer narrows down the options to FreeFileSync.
I'll search the documentation.
According to FreeFileSync forum the tool does *not* respect hardlinks[1,2].
However, in the same forum they recommend the commercial tool SynCovery[2,3].
There are downloads packaged for debian, and a free one month trial.
Haven't tried it, yet.
My thanks to all the responders.
