Thank you very much for your input and I think I got exactly what I needed to hear. I come from a PC background, my PC is on 24/7 and if it wasn't for that MS company that forces restarts, my PC would be on year in and out. The Carbonite is built to high standards, so it should be fine then to leave it running.
To clarify the monitor issue... The PC 2nd monitor goes into the Carbonite as a video feed. If the Carbonite is off, the PC/Mac doesn't pick up that there is a second monitor and then disables it. When the Carbonite comes on, those feeds show up as blue unsynchronized feeds and we have to manually set up the 2nd screen again, or unplug / replug the hdmi cables. It would have been handy if Windows and Mac had an option of always saving the 2nd display optio s even when it is not connected.
But leaving the Carbonite on will solve all this.
Thanks!
