I have being testing FreeFileSync 5.5 to see if it is possible to sync one
directory tree to multiple locations. In testing it appears to work and you
can sync this directory tree using different replication options(eg mirror to
one location and use automatic to another location. The intention is that the
synchronisation will take place on a regular basis. I just wanted to check
that the product can truly handle this scenario and that I won' t lose data or
cause synchronisation issue down the track.

There is no problem having one source and multiple targets. But you might want
to make sure there is no race-condition on a specific folder, e.g. a folder
participating in multiple pairs is read in one pair, but written to in another
pair, or written-to in multiple pairs. Since FFS first compairs, then syncs,
these changes will not be considered for the subsequent folder pairs.
FFS checks for this kind of race-condition and issues following error message:
"A folder will be modified which is part of multiple folder pairs. Please
review synchronization settings."
