The new beta has not backed up all the files and folders.
For example, one folder in Gdrive has 14 subfolders and 3 files but Syncdocs has only backed up 4 folders and 2 files.
I have examined and compared the sharing status of the backed up items with the non-backed up items and can see no pattern. I can confirm that the administrator user account that Syncdocs is using has edit rights to the files and folders that were not backed up.
General Aside
For us Google Drive has been a nightmare. Almost every week Google Drive loses important files belonging to one or two users and when I look in the Syncdocs backup it seems to be random chance whether the missing items are there.
I can see from searching the web that many people have similar problems. On the other hand millions of people are apparently happy with it (I read somewhere that 40 million people are using Google Apps).
What, I wonder, is the secret magic setting that makes the difference between Google Drive being OK or an nightmare?
