I have a burner Osiris but I burned all my mp3's to disk, then when my son formatted my computer one of the disks wouldn't work so I plan to back up these photos in several ways to be ultra careful with them.
My advice here (it's informed advice, not 'pulled out of thin air advice'!) is to recognise that no media is perfect and all the home recording media have a limited lifespan. For files or other images that are unreplaceable, my backup strategy is this:
1) Buy two different brands of CDs. Be careful here. You need two different brands which are *actually* different. A little web searching will reveal that a lot of the brands you see in stores are actually just rebrands from a small group of manufacturers.
2) Burn two copies of your files onto each brand.
3) Place one of the sets at a different location. Your desk at work, a parents/childs/trusted friends house. Offer to do the same for them.
4) Store the disks in a dark, dry, cool place.
4) Refresh (ie reburn) the files at a very minimum every 2 years. The dyes used in the disks do break down over time. This will happen very quickly if there is a fault in the disk allowing air in. I'd consider a yearly refresh to be the best way to do it.
Hope this helps
Also, I trust the online sites for backing up important files about as far as I can throw their data centers. You never know when they will simply cease to exist.
