#182937 - A good PSU is a good investment - backup policy even better Responding to: ???'s previous message |
The more expensive PSU do have internal overvoltage and surge protection, besides that mandatory "power good" functionality.
But in the end, everything that can fail will fail. It's jut a question of probability - if some other failure will terminate the device earlier. So important data should never be stored only on disks powered from a single power supply. Even more than that. Important data should also exist as off-line copies. And finaly - there should exist copies off-site, in case of a burglary or fire. Running software with "trap-door" functionality, it can be very good to have a small storage server at home (or at work depending on what files to protect), and duplicating all important files off-line directly. Just that the duplication functionality must not overwrite existing files - a changed file should be a new generation of the file. |
