I use TDPS on WHS 2011 (based on Windows Server 2008 R2). I do not want any of my files stored on any other server e.g. your servers. I am not saying that your servers are insecure just that I don't want my personal data that is under my control stored on anyone's servers!
During a setup on an account on a new Windows laptop, the default was to use the TeamDrive servers. I quickly changed this to use the TDPS. By doing this, did it remove all files from your servers?
How can I verify that there are no files stored on your servers?
Many thanks for a good product.
