>A personal NAS doesn't have the seamless backup of cloud storage> Synology has various plug-in's/apps that with either synchronize with cloud storage options (i.e. DropBox, OneDrive, etc.) - or backup to cloud storage. (No, I am not shilling, just been a happy customer of theirs for about 7-years, store about 20tb on my local 5-bay NAS)
