Data is something that's very valuable. Even exceed the value of the storage media. We lost a mobile phone, a computer or a laptop or even a flash often lament how precious data in it, such as documents and important papers, project data, assignments, thesis, and much more.
Writing on my personal experience, how sorry I have omitted an important file, i might be able to make it back, but considering the time I had to go through to write or create the data, makes me even more depressed.
