Answer 2

Keeping data backup is very essential for any user who have important data, the reason for backing up data is sometimes the data we store on the machine may get lost due to the machine failure. In case such situation arises, the lost data can be recovered from the place where it was backed up.

As backup is also done on some personal data storage device, it may coincidentally happen that all the data in the machine as well as in the storage device gets non-recoverable, so to avoid such cases online backup is preferred.
