In addition to making sure you back up your data regularly, there are a number of things you can do to prevent data loss.
Keeping your computers in a cool dust-free, dry area will help the machines stay healthy and working properly, preventing unexpected breakdowns. Heat is the number one killer of computers, so keeping them cool is vital.
Uninterruptible Power System
Even small bursts of energy can actually erase data on hard drives, while large power surges can go so far as to destroy computer equipment. Having a backup power supply prevents data loss not only during these power surges, but also during incidents such as lightning and electrical storms, by making sure your systems never shut down unexpectedly.
Another cause of data loss is viruses. To help prevent this, stay vigilant about what you download and the files you open. You should also make sure to keep all of your virus detection programs updated.
If you want to detect the problem before it becomes a problem, there are some software programs designed to spot these impending problems.
Sometimes your computer can be in the middle of running programs, even though you aren’t necessarily aware they are running. Shutting down your computer abruptly can disrupt this process. Make sure to save your data and shut down all applications before you shut down your computer.
