Data represents all the business activities, whether it is global organization or small enterprise. These data are back bone to business. Any loss to such a data can bring business on the verge of destruction. The data is generated on daily basis, by server, network, and multimedia and software application.
All these data are accurate and centralized and has to be available at the moments notice. Non-availability of data can affect the business.
At some point or the other you loose the data, either because of something very serious like system crash or either because of accidentally deletion of a file. It was believe earlier that data loss is a result of natural disaster but it account to only 3%.
Data loss is more frequently caused by hardware failure which amount to 44% of data losses. Human errors results in 32%, software error results in 14% and due to viruses 7% losses occur.
Now we will look into the 32% of data loss which occur due to human loss. These losses generally occur due to accidentally deletion of a file or spilling of coffee on the computer system affecting the hard drive result in data loss. While sometime re-installing a fresh copy of Windows without keeping the back is another cause of data loss by human.
Many computer users believe that once the photo, pictures, songs, or other files which has been deleted cannot be restored. But this is not the case; every file which has been accidentally deleted can be retrieve using data recovery software.
But data should not have got corrupted or over-written. What happens when a file gets deleted from the hard drive? Deleting a file only erase the index that window uses to retrieve the file. The file remains intact on the hard drive unless overwritten with new data.
