Cloud service, that synces CaptureOne Projects safely.

Today I use Resilio Sync as Cloud storage. Its what you fall privat Cloud. In teori it works as it should.
One server at Office, one workstation at Office, one External hard drive for laptop and some more computers.

Major problem is on the road with the laptop and the External hard drive. Perfect in sync when I leave the Office.  
You sitting in a Hotel with newely imported RAW, editing. Not to good Wifi so the synce to other computers is not finnished when you have to leave. 

So often when you get a good connection and time it works perfect. 
But some times the project database get corrupted. 

What Cloud service do you use. Dropbox don´t  work well for me. 

Hopefully CaptureOne comes with something now when the iPad version.
