When lightning and overvoltage shut IT down in the summer of 2008, as well as in the summer of 2009 there are two similarities: 1 for large parts of the summer due to rain in the water fell. 2. both summer were marked by strong heat thunderstorm and it can be presumed, that also the coming summer are likely to be similar. The devastating impact that lightning strikes (and the accompanying this voltage peaks in the mains) on IT, can however prevent himself. Private users or companies worry about the preventive measures do often to prevent data loss due to lightning and overvoltage or they do this often too late. There are many possibilities, to protect against overvoltages: IT decoupling: during lightning storms, unplug.
The power connector, as well as the network cable from the PC or notebook off. Use of Sockets with protection against overvoltage: often these power strips provide a filter for the devices connected to the network with RJ-45 Interface. Use of uninterruptible power (UPS) for offices and companies: here is to ensure that network connections also are also protected against any surge. Please consult your PC store or your House: after possibilities as you can protect from voltage damage your computer. From the point of view of data recovery, stress damage in terms of resulting data loss and the subsequent Cleanroom data recovery be considered always, what is basically right.
In addition a proper surge can however also ensure that many at that in-house mains connected devices do not work after a lightning strike. Based on a standard PC a surge can damage both the power supply of the PC, the motherboard and the hard disk. Other components within a PC or notebook can suffer serious damage due to overvoltage.
