This thread is a dumpster fire, routing infrastructure, solar panel addresses, we are adding this to EVERYTHING WE ALREADY HAVE that is growing exponentially. I work on an L7 support team, regular users are clueless on how this stuff is setup and apparently have strong stupid opinions. Anyone still reading disable ipv4 in your home network and try to roll forward. You will fail, and finite numbers are finite.
4 bay nas 22tb drives = 88tb as a single volume. Backed up to offline single storage drives that are timestamped. Anything newer than that timestamp gets rsynced/robocopied to a new drive until it’s full., update timestamp, swap drive and rinse repeat. If a drive fails, just replace it and copy the contents of the backup drives to master and restored. Alternatively you can set a single disk tolerance raid.
