Some of these people have mentioned online storage but not the majority. With online storage becoming a very inexpensive way of saving things, I believe this one method will be certain to be utilized more in the near future. A good reason may be the latest invention of wifi on an SD-memory card making it that much easier to get your photos from your camera directly to your online account.
For me, the actual transfer from my camera to my computer is the first step. Then, because ALL OF MY COMPUTERS are using CARBONITE, I know that this will also backup my photos. But since I typically do not want to fill up my hard drive with photos, and I will want to share some of them with my friends, family and the public, I will then publish my photos to my FLICKR account, using the RAW image mode for archiving purposes. Subscribing to a 'pro account' gives you unlimited uploading and storage of your photos so this is a no-brainer for the $24/year fee. Remember if you are planning on using external hard drive and/or cd/dvd discs to back things up, you need to be able to place the media in to a fire-proof safe (or your bank's safe deposit box), but whatever you do, it must placed somewhere that you can retrieve them easily enough and is still safe enough from the natural disasters in life.
