You should never use any scrape interval greater than 2 minutes. Prometheus considers data more than 5 minutes old as "stale", unless you've tweaked other settings (and it's not recommended). https://www.robustperception.io/keep-it-simple-scrape_interval-id/
Don't worry about storage. Prometheus compresses extremely efficiently, so even if you scrape the same data 30 times, the delta between them is zero and it will take almost no storage space at all.
