Yes, I would be interested to know that also, as how can a cron job (essentially *nix flavour) run on a Windows server.
The message is …
BackUpWordPress has detected a problem. wp-cron.php is returning a Operation timed out after 5008 milliseconds with 0 bytes received response which could mean cron jobs aren’t getting fired properly. BackUpWordPress relies on wp-cron to run scheduled back ups. See the FAQ for more details.
We are also getting a message
BackUpWordPress is almost ready. The backups directory can’t be created because your wp-content directory isn’t writable, run chown phx3\iusr_**********: D:\Hosting\********\html/wp-content or chmod 777 D:\Hosting\********\html/wp-content or create the folder yourself.
When I try to make the /backups path writable with Filezilla it says
500 ‘SITE CHMOD 777 backups’: command not understood
Yet, the docs for this plugin state it will run on Linux and Windows server. I have emailed the support, no reply as yet.
WordPress uses it’s own cron abstraction, it doesn’t use unix crontab.
Could you try version 2.2 to see if that resolves your issue.
