Personally I’m not archiving current stuff (current applications for example, except operating systems in ISO image format) and I’m not too worried about RAID 1 or special NAS hardware/software. Basically I’m archiving stuff that will be hard to find or impossible, stuff that I might enjoy to browse through someday, old photos and videos, old movies, etc.
