When Craft tries to apply an update, it tries to back up the database. Although that's great in general, backing up a large database using PHP requires a lot of memory and resources that might not be available in the hosting environment or the client does not have enough access to make any related adjustments.
Is there a setting of some kind that would prevent Craft CMS from backing up the database when updating? I already use a command line script to backup the database before applying an update.
