Having issues with this question:

Your task is to create a crontab setting that can automatically backing up the files in your home directory to an external drive $($could be a flash drive, external hard$-$drive, or cloud$)$ everyday at a certain time. Turn in your crontab file $($copy and paste, or in an attachment$)$ and explain how you set it up$.$

You are not allowed to use 'tar' command. You may use $\text{'}$rsync$\text{'}$ command instead.
