 * Hi,
 * I’m having trouble understanding why I’m unable to create backups with UpdraftPlus.
 * I’m getting a “Binary zip: error (code: -1)” when I try to back up the files (
   the database backup works fine).
   Here are my logs: [https://pastebin.com/TbJ6i4gx](https://pastebin.com/TbJ6i4gx)
 * Could you please help me figure out why it’s not working?
 * Thank you,
   Maxime

 * Hi,
 * I think there might be an issue with your site scheduler. Can you install the
   free plugin WP Crontrol and go to your Cron Events. Are any of your events showing
   as overdue?
