Run toucan automaticlly for a backup using a password

Hello

Thanks for the great software of toucan!!!! Just a question:
I want to start toucan automatically one time a week to make a backup of some files using the option to use a password for the backup zip file. Is there a possibility to make this? I try with the task sheduler of microsoft and a .bat file. It is working but without using a password. Do somebody knows a way? Perhaps also without using the task sheduler of microsoft (usefull, when I am using the software on an other computer...).

Thank you for your help!!!
