I've got a Mac mini that I would like to run headless; leaving plugged in to network and power only.
I want to leave the Mac mini on to:
Run Dropbox constantly, so that I have the local copy backed up to the Mac mini.
Run a cloud backup service so that my Dropbox data is backed up again.
The hurdles I see with doing so are:
If there is a power cut, I want to make sure that the machine reboots and logs back in so that tasks 1. & 2. above can run. This can be partially achieved by powering the Mac mini via a UPS, although if the power cut was long enough the UPS would also fail.
Knowing if the systems fail, so that I can fix them. I wouldn't want the systems to fail and me not know for 6 months.
Are there some specific settings I should be looking at in macOS to enable me to leave it running constantly carrying out tasks 1. & 2. above?
