It really doesnt matter much imo. The obvious best choice here would be three copies on three media in three locations. You can also argue for more. It depends on your threat model. If you have an offsite backup that is reachable from the host machine, a ransomware attack can still devastate you. I have therefore made deaddrops for backups so no machine or user has access to all of them.
Comment on Is a cloud backup an acceptable backup for a home server?
BearOfaTime@lemm.ee 4 months agoI dunno about 2 copies on one drive - they’re both at risk of the same drive failing, etc.

Yeah, but if your house burns down copies on different hdd wont matter much. Offsite like cloud will
