I store my pictures on my ipod (as a backup) but somepeople says it's not good idea, is it?
i don't put lots of pictures but i do not want to lose them.
Back them up to CD or DVD, it's the easiest and you shouldn't have to worry about loosing them. They're a lot safer on a solid-state disc than on the drive in an ipod. If something happens to your ipod, the photos are toast...
I think it's alot cheaper to store them on DVD or CD like Will suggests. That way you can have several backups in case one of the discs is damaged or corrupted etc. Personally I also keep all my images on the hard drive, so I have easy access to them if I want to experiment.
"A piece of toast with butter always lands butter side down, and a cat always lands on its feet. What happens if a piece of toast is tied butter side down to the back of a cat? Does it perpetually hover above the ground in indecision when dropped?"
The only problem with CD/DVD media is shelf-life. Don't assume that even "archival" cd-r's will last forever. It's pretty widely reported that 5-10 years (which is still a long time) is the life span of recorded media. I've heard library stardards recommend re-recording media every 5 years, if I recall. I was asked to recopy some Kodak photo-cd's that had been around for 7 years or so, and several of the discs wouldn't copy 1:1 (exact duplicate). I could, at least, read the files and reburn them, but this pretty much made me assume that some degradation had occurred, even in the "archival" "gold" CD's done at a Kodak lab. My boss told me they had spent quite a lot of money having those done at the time.
Edit: I didn't note before that these CDs had spent that time in a cabinet drawer and were used infrequently, so there was slim to no use/light degradation.
Photos on an iPod should be ok, assuming it's not lost/stolen or the drive goes bad. You may want to back up your back-up. :)
If I had a really good photo that I wanted to ensure safty for then I would have it printed out at a really large size by a service like daprints. Sure, rescanning wouldn't perfectly reproduce the photo digitally, but it would be a lot better and easier than continually testing an rewriting a digital backup.
Yea, I know they use quality stuff, the things I've bought are gorgeous. It was more a warning about doing-it-yourself... and stuff... since I like to be the rain-on-the-parade. :-p
Re: the CD-R longevity issue, I have discs that were written back in 1996 that still read fine, with no loss of data. I have yet to have more than a couple go bad on me (touch wood), and I have hundreds and hundreds of them in storage (The majority of them being written after 2001).For some really important work, I have had transparencies made from the digital files, but the cost is prohibitive in the majority of cases.
