A file synchronization tool that respects hardlinks

[Itay <debian@itayf.fastmail.fm>]

Hi

I have two machines for which I need to sync my home directory.

The sync must be bidirectional and respect hardlinks because many subdirs are kept under the control of darcs[1] which by default uses hardlinks.  The sync tool I used in the past, unison[2], does not respect hardlinks[3].

According to wikipedia[4] the following tools are bidirectional:

     FreeFileSync / NextCloud / Owncloud / SyncThing

Please -- can someone quickly tell me if they respect hardlinks?

Or recommend another tool(s) that respect hardlinks?

Thanks in advance.
