Online/offline syncronization

If Tryton is installed on a server in a cloud centre, is it possible to also install a version on a local server and enable syncronization?

The question is really about a business with a central admin operation in the city, and Prestashop need to be linked to Tryton in the cloud, but there is also a remote operation with unreliable connectivity that needs to record receiving and production information as well as shipping documents. If the internet line goes down, they still need to continue.

No, such synchronization with PostgreSQL is really not option.
It will be much cheaper and more reliable to buy a second backup internet connection (ex: via 4G).


In some areas they lucky if they get 2G at times. Probably need 2 installs with kind of integration layer to exchange critical data bi-directional.
