Hi,

When I have let Smart software to back up all the data on my partition C into My Passport, I didn’t see that the files which synchronized  ‘Google drive’ backe up, although the files synchronised to Skypye, Dropbox  and CX  were backed up.

Any comments would be quite appreciated

I tried myself and is true, the dropbox folder is backed up but the Google Drive is not, even if you switch to file backup the folder appears grayed out.  I am guessing that maybe Google Drive uses some kind of encryption that interferes with SmartWare.
