That's what I've been struggling with for the past 6 months. I had to wipe our laptop's hard drive, so I moved everything to an external hard drive. But, I lost our external hard drive that had every single picture of DD on it since her birth. It's been killing me - every night I think about how I'll never get to have those pictures again.
But, this morning I found out that I actually had a Dropbox account set up, and it had been backing up all of my pictures and videos from my phone since she was born. I'm so happy right now, I could cry. I still lost all of the nice, DSLR pictures, but I don't really care
What would you do if you lost all of your LO's pictures?
