Time and effort wise it would be unsmart to not keep them properly backuped up. Otherwise reripping 4-8tb of data is time consuming. 25gig costs 50 cent / month to store on something easy like google drive. For keeping a zfs cluster up and running and maintained, its probably way cheaper but still you pay for power, hardware and your labour.
