Hi, I am looking to have a system that backs up my 3 storage drives (1 ssd, 1 had and 1 ext hdd) and potentially my wife's laptop hdd. I don't know if it's better to have each drive just clone to a dedicated drive or shove all drive on one monster hdd? I have access to old pc's if that helps. Looking to backup about once a week. The drives in their entirety. What's the cheapest way to do this?
