That's a good point Khendar, we are trending towards a time where it will be less and less important to own media. Why do you need to back up your music and movies if you can stream all if it, any time from many devices? I know we are not there yet, but its foreseeable that we could be there soon. Meh, who am I kidding, the RIAA will screw it up.
I need/choose to because
a. I don't have the bandwidth i would take to replace them all
b. it seems like it would take longer to track everything down again, rename every file properly, than to just save them.
c. because if it's illegal, it'll take ages to one-by-one turn your own CDs back into mp3s, or the files were illegal downloads, not illegal converts, it might not always be so easy to re-download them (imagine trying to restore a collection dealing with some 100k throttle 20-minute-wait-period host because all the good sites have been scared off by the FBI), and if it's legal, you'll have wasted your money--you can't say 'it was stolen, iTunes, so please let me redownload the songs I bought'
of course...who really fuckin needs all their shit? I 'lost' about 300 hip-hop albums I had...about 5 years ago. I got my favorite songs, my have yet to give enough of a shit to so much as catch a free download of any of the albums. I probably do spend more time plugging in and unplugging my backup drives than it would take me to just start over some day.
