Since I run CrashPlan on my QNAP to back up my personal data, yet I still want to use the CrashPlan GUI on my Mac, I don’t need the CrashPlanService running in the background on my Mac all the time.
In retrospect I should have seen it coming. I have an external monitor at work plugged in via displayport, the other port connected to my thunderbolt ethernet connection. Once while accidentally jiggling the ethernet adapter my screens went black for a second (looked like the resolutions needed to refresh or something, screens went black, then came back a few seconds later). Freaked me out, but the displays came back. Anyway, as I said, I should have taken that as a sign that something wicked this way was a comin’.
Fast-forward a month or so. Before work, morning coffee in hand, open the lid, login prompt appears. I get an SMS on my phone, so my attention diverts. Read the SMS, reply, etc. A few minutes later I go back to my Mac, the screen black as usual, as it has powered down since I didn’t log in for a few minutes. Or so I thought. No amount of key presses, opening-and-closing of the lid got the screen back to life. The keyboard backlight was on, I knew the Mac was on. Close lid, wait a few minutes, open lid. No screen. Ok, power off and reboot. No screen. At all. Ok crap. Starting to stress now as I will be late for work if I don’t leave soon. Scramble in the cabinets, looking for any monitor cables. Found an HDMI cable. Plugged the Mac into the TV. No video anywhere, black on both screens. Ok, reset PRAM (command-option-P-R at boot). Nope. Reset PRAM a dozen times. Nope. Reset SMC (left shift-control-option-power). Nope. Reset SMC a half-dozen times. Nope. Still black screen.
It’s happened to me twice now: CrashPlan stops backing up my files apparently due to a failed software update. I usually don’t know CrashPlan has stopped backing up until I get the weekly email status update. Fortunately, the files that I back up to CrashPlan are not changed often at all, and missing a backup for a couple days isn’t the end of the world.
My homemade server running Ubuntu started to experience strange hardware issues (random crashing, etc). Over the course of a year I replaced and fiddled with memory, motherboard, and hard drives yet still I had random crashes (would even randomly crash running memtest, so I ruled out a software issue). Since the server was my home NAS, I began to rethink the idea of maintaining unreliable hardware (and throwing money away left and right).
