I like to add “0”… which somehow relates to not having untested restore systems.
Just realised my primary, backup and offsites are all spinning platter disks. When they say two types of storage, what does that mean exactly?
Differing kinda of storage in case one doesn’t work with the device being restored to, or something happens that’s more likely to affect one type of media than the other. A strong electrical field could scramble the hell out of spinning rust’s magnetic media, while doing nothing to optical media, for example.
For home use it’s decent enough to have 2 copies, and 1 off-site.
Especially if 1 of your copies has some kind of redundancy, like RAID 1.
who can afford that though?
I’ve got 3 local copies. What are you gonna do about it?
Fr tho, main pc, NAS and laptop. Trying to help friend build a NAS and then swap offsite backup space.
