Time machine backup with pnpm

[ApolloTang]

After reading
https://discussions.apple.com/thread/5650885
and
https://superuser.com/questions/166895/how-does-time-machine-deal-with-hard-links

I am still not clear how hard links are backed up in the Time machine on OSX.

Basically, I want to know, when using pnpm and backup with the time machine, will each of the hard links created by pnpm be duplicated and result in bloated backup?

Thanks if anyone can help to answer my question.
