I am giving this plugin another shot after never getting it to work.
I am using Google Drive as my offsite location. I went through all the setup as requested and filled out the Google Drive ID, Secret, Folder Id, Redirect URI, and authenticated (I get the "You appear to be already authenticated" message).
I run the backup and receive an email. Toward the bottom of the email I see:
Mon, 07 Jan 2013 19:22:53 +0000 Google Drive error when requesting access token
Mon, 07 Jan 2013 19:22:53 +0000 Error message: SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
Mon, 07 Jan 2013 19:22:53 +0000 ERROR: Have not yet obtained an access token from Google (has the user authorised?)
Also, when I click the "Test S3 Settings" I get the error, "Failure: No bucket details were given." (perhaps this button isn't supposed to appear when Google Drive is selected?)
Also, the /wp-content/updraft directory is empty.
I am using version 1.1.15 on WP 3.5
Any help is greatly appreciated!
