Which free cloud storage to choose for a specific task?

Question

Google

There is an office, a server and a remote employee (such as a traveling salesman).
I would like to allocate a folder on the shared disk, where office workers could, if necessary, throw "heavy" documents for the salesman (Word, Excel, presentations, photos, videos, etc.), and the salesman's laptop was synchronized with this folder when accessing " "cheap" internet (Wi-Fi in the hotel, etc.).
Accordingly, the client on the server must be run as a service, the client on the laptop - manually.
DropBox with free 2G is fine in principle, but as the service does not start, you need to monitor that the server has not rebooted after an update or power failure.
What do you recommend?
