It appears that Intuit may be trying to prevent syncing these files in this way. There are resources that strongly recommend not putting the raw QBW files into a sync system:

Here is a more in-depth post about the risks: http://longforsuccess.com/advice-for-using-dropbox-sugarsync-or-box-net-with-quickbooks-or-quicken-files/
Essentially, QBW files are databases. They are updated constantly and synced constantly. Quickbooks will continue to write to and access these files as long as it is running. Once you introduce a multi-instance scenario, things can start going sideways really quickly.
I have a feeling that Intuit started write-protecting the files in an effort to prevent remote updates, keeping all changes local to the system instead of updating from the remote source.
Given this information, I would recommend not using qbw files directly out of odrive, but you can use it for storing Quickbook backup files.
