tar --exclude='./dir2ignore' --exclude='./cache_etc' -zcvf /backup/myarchive.tar.gz .

So geht es:

drush php-eval 'my_custom_module_cron();'

Controller könnte so aussehen:

<?php

class myController extends ControllerBase
{
    public function myFunc1()
    {
        $html = " ... ";
        return [
            '#type' => 'inline_template', 
            '#template' => '{{ html|raw }}', 
            '#context' => ['html' => $html]
        ];
    }
}

Command 1:

drush sql:dump  | gzip -c > /home/backup/db-$(date +%Y-%m-%d-%H%M).sql.gz

Error:

mysqldump: Error: 'Access denied; you need (at least one of) the PROCESS privilege(s) for this operation' when trying to dump tablespaces

Lösung:

drush sql:dump --extra-dump=--no-tablespaces

Code:

 find / -name art  2>&1 | grep -v "Permission denied"
