As far as I’m familiar, an intuitive, ready to use and free platform for handling data (I assume, of the scientific type) and metadata is not developed, or successfully marketed. I agree with people above: a well-known cloud storage solutions are the best solutions at the moment. In fact, an open access to their API, allows a relatively easy integration of LabVIEW with these cloud storage platforms and several different LabVIEW interfaces can be found here, though I cannot guarantee if the functionality will meet your expectations:
Google drive
Amazon S3
If you are willing to invest a bit of time customising and hacking the software, you might end up with a pretty good solution for yourself. I think there shouldn’t be a problem writing an interface that would allow a smooth LabVIEW connection with Dropbox using their HTTP API
I’m personally familiar with the people who are developing a cloud storage platform https://rinocloud.com/ for the purpose you are asking – cloud storage of data, metadata, sharing,… Pretty much Dropbox, but optimised for scientists. At the moment it’s in a testing stage, however, if you don’t want to invest your time writing your own custom software, I would recommend keeping an eye on them or signing up for a beta testing, as they already can provide LabVIEW (plus MATLAB, Python,..) code for a smooth integration between your measurement software and the cloud storage server.
I hope this helps.
