You have less than 35 MB of free disk space on the disk

Hi Emily,

this is down to the storage of the application that you are using in Building your website”

That’s not correct – it doesn’t refer to remote storage (e.g. Dropbox. Google Drive). This message is the result of calling PHP’s disk_free_space function – https://secure.php.net/disk_free_space – and refers to space on the physical disk that your website is on (i.e. not to your web hosting account quota – but the physical bit of hardware that the site is on).

If it persists, you’ll want to point your web hosting company to that link, and then they should understand the issue.

Best wishes,
David

Hi Emily,

That reply you’ve had from them isn’t making much sense… that part of the code is both a) identical in the release and development versions and b) also doesn’t trigger if the disk_free_space() check fails. Here’s the code (in both versions – it’s not had any changes for a long time):

if ($this->disk_space_check(1048576*35) === false) add_action('all_admin_notices', array($this, 'show_admin_warning_diskspace'));

        private function disk_space_check($space) {
                global $updraftplus;
                $updraft_dir = $updraftplus->backups_dir_location();
                $disk_free_space = @disk_free_space($updraft_dir);
                if ($disk_free_space == false) return -1;
                return ($disk_free_space > $space) ? true : false;
        }

The PHP manual – https://secure.php.net/disk_free_space – says that disk_free_space() “Returns the number of available bytes as a float or FALSE on failure.” Note that the function disk_space_check() above returns -1 both if the disk reports zero bytes free, or a failure – and doesn’t trigger the dashboard notice. The dashboard notice can only trigger if disk_free_space() returns something that’s both greater than zero, and less than 35Mb.

Do you have a vaguely current version of UD installed?
