Death of a Server

    Youch, yeah happens. I’d replace \electrically isolated\ to offsite, especially for photos. Ship a dsl/cable enabled friend/family a driver, or backup to S3 or something. Use rsync, one of the rsync based, or duplicity (if to s3).

    Sadly UPSs provide minimal if any protection against spikes unless they are the more expensive, heavier, noisier, and hotter fully online variety that continuously puts the power from AC -> DC -> AC again. Of course powerstrips are even more limited in their protection. To test just unplug your UPS, if you hear a loud click then it’s not online and you can hear the latency between power flicker and UPS switch over.

    Hmmm, there’s a big loss going from ac -> dc -> ac -> dc (wall -> ups -> power cable -> power supply. I wonder if laptops run online… if so a usb drive connect to (and powered by) a laptop might be significantly more reliable than a usb connected to a desktop.

    BTW, typically only the 2.5\ drives can be powered by USB.

    Not sure a surge that destroys a power supply, motherboard, and down the molex connect to 3 drives is going to stop just because it’s going over USB.

    Where any other computers online, in the house, and fine?

    Bill,

    I actually have off-sites for most critical things. Like photos. But there is a delay while “I process, copy, etc”, photos I’ve just taken. I think I may change this process to include “backup right away” now…

    And you’re right, UPSes aren’t fantastic. But they’re still “better than nothing”. I’m still fairly confident that it was the PS itself, but you’re right that there was always the chance it wasn’t.

    Personally, I think we should do 12V around the house and have a converter at the edge. The DC lines in a house should be short enough to limit the voltage drop to a reasonable amount.
