No, a home server doesn't violate the rule. It is "Location #1". So long as location #2 is someplace else, a local server is OK.
In my case, All my data is on a Synology NAS. This data is backed up to another Synology NAS that is in an upstairs bedroom closet. The backup runs continuously. The primary NAS is also backed up by a cloud service (Backblaze) There is no important data stored on the desktop computer. Plce all the data on the NAS means that I never have to move data between computers. I have a primary system that is Linux based. It is a 16-core xeon workstation. There are also a couple iMacs and Mac book n the house and some other computers that drive some CNC machine tools and all of them go to the NAS for data.
