That's definitely a very big library, but you should be able to upload that to both Google Drive and OneDrive, so I'm not sure why you are encountering those errors. It may be that the code or library (or both) that I'm using to connect to those services is just not robust enough to handle errors in the connection. I would like you to try something for me:

1) Create the library backup file on the device itself.
2) Try to upload that file through either the OneDrive application or the Google Drive application
3) See if you run into any issues uploading the file

I'm assuming you've already verified that you have at least 3 GB of free space in your cloud accounts. If you do think there is an issue with special symbols in file names, please let me know what names to test with so I can try reproducing those problems.

Thanks,
Mike
