Backups are vital for a server in company. At work we do a backup every day. At home, it depends how important your stuff is. For pictures you should always copy them on DVD. I regularly backup pictures for people who have ususable windows systems, for 
them the pictures are the most important stuff but they do not back them up.

Personally I don't like to do regular backups because that involves too many DVDs. I probably should do my backups more often.
I do have 3 2TB hard disks with important data copied on each for redudancy. I also have some backups on a 500G driver which is not powered usually. I also make some backup on DVDs sometimes.
Anything that is of extreme importance I have in several DVDs which I make copies of every few months. I remembered that in the early days of CD that their life was rather limited and am not taking chances on DVD even though I think the technology is a lot 
better.
