Hi folks,
I'm trying to create a system for myself where I have a two-way sync between my storage on Dropbox and my main external hard-drive, connected to my home desktop. I also use two laptop computers for work (teaching) and for performance (music), and these activities overlap a lot. I use Dropbox to good effect across all machines, but I have not been good about backing everything up online and my other backups are split across various devices without good filing.
Basically I'd like to organise my filing with the external drive as a hub (4TB), with everything backed up on Dropbox as a mirror but not necessarily be present on the SSD on the desktop (to keep free space where possible). I imagine this will require 3rd party service. One issue I'm anticipating is that a 3rd party solution might run into problems where the external drive is not online and Dropbox might mistakenly think files were deleted. Hoping to get some insight and advice from users here.
