Offline Sync between two disconnected computers

I have two computers that are not connected to a network that I would like to sync. The computers are physically distant from one another and connecting them to a network is against the security policy. I would like to sync part of the file system of the first system to the second. The first system generates data that will need to be moved to the second system. The second system is only used for viewing the data. If files/directories are moved/deleted/modified on the first system, the change should be mirrored onto the second system when an update is performed through intermediate external hard drives. I would like to do incremental rather than full copies as the amount of data exceeds 5 TB. Does FreeFileSync (or any other product that anyone is aware of for that matter) support such a goofy setup? I had hoped to find something so that I didn't have to cobble something together myself. Thank you.

Bump! I believe this is something worth having. Maybe GIT-like behavior can be leveraged to achieve something like this? One can have the "remote" for a GIT repository on a portable drive, our transit media here. Pushes and pulls from remote already do only incremental so as space on transit media becomes low, the actual objects could be deleted from the GIT repository, making multiple device able to sync up from a given snapshot at a point in time, not necessarily able to clone the whole thing.
I am not suggesting this could be done with GIT as is, just noting the strength and possible use of the versioning approach. FreeFileSync seems to have a lot of this in it, maybe it can do it with its own approach ;)

As both computers are not connected, you would always need a portable data carrier being carried back and forth between the two computers, e.g. your intermediate external hard drives.
You require that "If files/directories are moved/deleted/modified on the first system, the change should be mirrored onto the second system". Because of the "moved/deleted" aspect, the only way this can be done with FFS (at least presently) is to have a single intermediate external hard drive that comprises all >5 TB of data, and does require you to run a FFS Mirror sync variant from Source computer to intermediate external hard drive, and then a FFS Mirror sync variant from intermediate external hard drive to Destination computer.
