It's not just PSU issues that can b0rk other drives that you need to worry about. not this one with TS on it I don't, but once you have a networked back up solution, you can use it for everything), so I'm not expecting anyone to go to the same lengths I do, but at least have a fast external USB3.0 drive or fast NAS system. I earn money with my computers though (well. I'd need 5 simultaneous drive failures to lose data. I also DO have separate drives inside the machine as well. Each of those servers is also RAID10 so each can stand 2 drive failures and carry on. I have a separate file server for back ups, and then that mirrors to another server in my garage to mitigate against a house fire. Click to expand.and a back up solution to prevent this from happening again, right? If your 'back up' was in the same PC as your other drives, then it's not back up.
