ive never done any kind of scripts before, but wanted to make a script which backup my home dir and make an output. is this a bad or okey way to do so? 
 ` ` `#!/bin/bash
rm hdd/backup/home/*.homebak
rsync -aAXv --dry-run --exclude={"hdd","ext",".var"} . hdd/backup/home --progress >> "hdd/backup/home/$(date +%Y%m%d-%H%M%S).homebak"
