Completely fails due to authentication problem: API changes, I think!

[GoogleCodeExporter]

Last ran a backup on May 4. Just tried to run one today (May 29), and it fails 
immediately, with this error:

GDataRequestException: Execution of authentication request returned unexpected 
result: 404.

Anyone else getting this?

I'm pretty sure that it's due to some changes in how the API/auth. is working; 
a quick DuckDuckGo search turned these up:

I'm assuming something can be done to fix GDocBackup; if anyone with experience 
of using these APIs has time to poke around in the source, that'd be great.

I can have a look, but not for a couple of weeks. And even then, I fear the fix 
won't be completely trivial, so I might not be able to help.

Unfortunately, it seems GDocBackup is completely unusable until then! If anyone 
finds a workaround, please let us know. :)

Thanks.

I have the same issue. Wont' authenticate. Do we just have to wait for a new 
version or is there some other form of workaround?

Hello everybody,

GDocBackup uses old Google APIs. The old APIs were shut down by Google. So 
GDocBackup stopped working. As I wrote on project homepage, I have no time to 
modify and maintain it. From my point of view, the job required on GDocBackup 
to use the new APIs is too big.
Feel free to contact me if you need more details or other informations.
