Where can I find some good info about computer data backup evolution and development?

mario,yourasked:

I need detailed information on the backup media, backup strategies, software, etc. for my studies. I am particularly interested in some historical or scientific research and comments on this subject. Could you please some good sites or books.

- Article high praise on the safeguarding of data history featuring storage devices, enterprises, software and so on. There are few statistics and illustrations. Hopefully it will be useful!
