2-way realtime sync
2 laptops, one for use at home and one for use on the road. I'm thinking a client based utility that backs up the home laptop onto a NAS box and before leaving logging into road trip laptop and the changes copied down to that laptop. Also when coming home, the changes from the roadtrip laptop updating the NAS box, and then these changes applied to the home laptop.
Stinger is, both laptops are windows 10. I'm wondering if there is a real time 2 way sync windows client between two laptops via a NAS box that is GNU compliant
Freefilesync sounded ideal but there is doubt over is GNU licence claims - https://trisquel.info/en/forum/synchroniser-deux-dossiers-sans-faire-de-copie-inutile
Syncthing needs a client running on the NAS. I'm not sure if my Netgear Readynas can do.
