I just installed the plugin and the connection to Google Drive is authorized. When I run a backup the zip appears in the local folder, but the upload fails:
2012-06-19 17:14:49 NOTICE Attempting to upload archive to Google Drive 2012-06-19 17:18:17 ERROR Operation timed out after 5000 milliseconds with 0 bytes received (http_request_failed) 2012-06-19 17:18:17 NOTICE Backup process completed in 245.12 seconds. Initial PHP memory usage was 38 MB and the backup process used another 51.5 MB of RAM.
Does this suggest some kind of restriction on my hosting account? I haven't encountered any problems with outgoing HTTP requests yet (for updates, downloads, plugins such as Akismet, etc).
Great plugin, thanks!
