I use the command
drush up for sites I store on a shared server & locally.
Within some months my Inode volume vent from about 25% 96% (96% is insane for most people using a shared server on whatever platform) and given the fact I already have 30 days backwards backup service, I don't really need this specific backup creation.
How can you disable the automatic backups created by drush each time
drush update is ran?
