🚀 go-pugleaf

as an alternative...
xcopy /k /o /x /s /e <source> [destination]
(comes with windows)
I've done large amounts of file transfers using it--up to 100 gigs or more 
and it works fine (but it's slow)

There are also flags to select files by date.  There's a flag to exclude 
some files as well, but it's clumsy.

Google it and you'll get a hit on microsoft's web site with all the 
parameters and explanations.

By far the quickest way would usually be to do a backup and a restore, 
however, if you've got reasonably fast backup hardware.
