I can’t tell you how many parents I know whose computers have crashed and have lost hundreds of photos of their children’s early years. When it happens, it kinda makes you sick to your stomach.
So I have a personal policy that my special photos must be stored somewhere besides my personal computer.
I usually burn the photos to a CD or DVD, but I don’t see this as a fail-safe plan because they would be destroyed if the house burnt down. (I know, I’m a little paranoid.)
To resolve this I have an account with Shutterfly and upload my special photos there. (Snapfish is another option.) There is no cost and no limit to how many photos I can store there. If, heaven forbid, the computer crashes or the house burns down, they are safe. I could download them or have an archive CD created and shipped to me.
