I'm using my Mac Mini as a TimeMachine host. I have a couple of external drives plugged in via USB. TimeMachine doesn't work unless I use Finder to manually Browse the network and mount the volume after each reboot or Wifi change (e.g. when I've taken the MacBook on a work trip).
Is there a way to have macOS or a script on my MBP to automagically mount the volume on the Mac Mini? Maybe something that checks every 30 minutes and remounts if it is not already?
Edit: I have two home Wifis - one super-fast 4G with limited bandwidth, and the default one backed by ADSL, so I switch to the 4G one when I need to videoconference, and back to the default one to use the printer or connect to other devices at home.
