What will need to be backed up?
-	confirm paths on screen
($HOME)
/var/www

Where will it backup to?
x	Prompt for current dir/new dir?
	Or maybe passed as an arg?

File name? Get the date and time automatically
date "+%Y%m%d_%H%M"

Command:
$timestamp = $(date "+%Y%m%d_%H%M")
$filename = "backup_$timestamp.tar.gz"
tar -czvf /tmp/$filename /var/www $HOME | grep 'tar:'

Save variables to a file in /tmp, and read them on launch
only way to save variables across instances of the script

Find a way to see grep returns no results and convey that to the user

Add option to generate a reusable run&forget script that'd work with cron for automation
Maybe ability to add an entry to the user's crontab automatically?
	line="* * * * * /path/to/command"
	(crontab -u $(whoami) -l; echo "$line" ) | crontab -u $(whoami) -
