| Don't Panic!
One of the main problems that occurs when we lose data is that we
start to panic. And when we panic, we push every button possible in hopes
of retrieving the precious information. But alas, we only add to the problem.
So what exactly causes the data loss? There are several problems that
can cause the dilemma:
- virus
- software failure
- file corruption
- hard drive crash
- server failure
- human error
- power surge
- natural disaster
Here you will find possible symptoms and examples of problems that led
to your data loss and how you can go about avoiding these problems.
Hardware or System Failure: 78% of data loss situations
