There is no doubt that you need to protect your data from loss as it contains your important documents and files which were prepared with months and sometimes years of efforts. Data protection is of two types:

• Data backup and restore: In this option, we need to back up the data as per our schedule. Whenever needed, we can restore the data from the backup. The data which was created or modified after the backup was taken is lost when we restore the backup.
• Data recovery. In this option, there are data recovery utilities which can help you recover your data even if you have not previously backed up your data.

To understand why you need to use online backup services, consider the reasons why you should backup your data in the first place. The answers are obvious – to protect against hard disk failures, unintended deletions and other causes of data loss. Online backup services come in picture in the other causes.
