A past client of mine recently emailed me, saying her computer had crashed and that she had lost all her wedding photos. "I was crying for days...I even paid Apple to try and get them and they couldn't..." she told me. She reached out in hopes I still had her images from over 5 years ago. I did.
We take for granted all the digital assets we have-music, images, video, documents....the list goes on and on. With digital cloud storage getting cheaper and cheaper, it's a good idea to look into moving your important files into the cloud, as well as having on-site backups.
I use Smugmug to store my images off-site. it's easy to access, easy to distribute, and I know all my cat pictures I've taken over the years will be safe. Thank god.
