My NAS runs OpenMediaVault.  It happens that mine is on a Raspberry Pi,
but it's available (at zero cost) for many platforms.  It's Linux under
the bonnet, and the file systems in my case are ext4 - I can't imagine
anyone would choose VFAT for use under Linux.

And rsync most definitely /is/ an option; I use it.
