Online backup of a complete hard disk is not practical to do. Although, it can be done. The size requirement and the transfer speed over the Internet makes it yet not powerful enough to do. However in the future complete backup of hard disks online will be more common. Backup over the Internet is best suited for storing limited numbers of specific files and folders.
To do this you need an FTP software which makes it possible to move files over the internet. FTP stand for "file transfer protocol" and is the most commonly used method of transferring files between computers over the Internet.
Use FTP transfer and backup to your web site or to a remote server as a safeguard of your vital data files!

Normally you don't need to backup all the content of your hard disk, to recreate your data.
To be able to make a full recovery of your data, make sure that you keep CD's of all your installation programs and operating system in a safe place. In addition, if you have installed software from the Internet you need to keep copies of the installation programs as backup together with the installation codes.
After you have done that, you need to identify the files and folders that are important to backup.
These are the files you use on a daily basis either in private or in your business. If you are using Windows this can be files in My Document folder and/or your Outlook email files.
These are the files you need to backup so that you can recreate your computer back to what it was if you have lost your data.
If you transfer files from your hard disk directly to the remote site you risk exposing your data to hackers. Your data are not secure from outside preying eyes.
To get full protection you should use a backup software to first create a backup file which is stored temporarily on you hard drive. This file is then transferred with an FTP program to the online server.
There are also a number of online backup services you can subscribe to for this purpose. They often use their own transfer protocol.
Online backups should be made at regular intervals. It is also a practical way to make backup if you use a laptop and are on the move, given you have access to an Internet connection, of course.

You must keep the server's username and password you are using as well as the password you use for encryption of the backup written down on paper in a safe place so that you can recreate your data.
Full backup can be made using other types of media such as tapes, DVD's, on different disks or on networks.
To do this you need to have access to such devices.
This will cost you money.
The memory requirement for today's computers has increased. The cost of regular backup on tapes or on DVD's is high.
If you are an entrepreneur or a home computer user, this may not be an option available for you.
