How can I fix my failing backup?

1. Increase PHP Memory Limit

  • Cause: If the server’s PHP memory limit is too low, JetBackup might fail to process all the files.
  • Solution: Increase the PHP memory limit in your php.ini file or through your hosting control panel:
    memory_limit = 256M
  • If you don’t have access to php.ini, try adding the following lines to your wp-config.php:
     define('WP_MEMORY_LIMIT', '256M');
     define('WP_MAX_MEMORY_LIMIT', '512M');

Restart your web server or PHP process to apply changes

2. Check for Plugin or Theme Conflicts

Cause: Some plugins or themes might interfere with JetBackup.

Solution: Disable non-essential plugins and themes temporarily and try running the backup again.

3. Review JetBackup Logs

  • Go to JetBackup > Backups
  • Click “Download Logs” button underneath the failed backup
