So I've been shooting at least in some form since 1999 and lost photos for the first time ever. My wife went to look for some photos she recently shot and they just weren't there. I also noticed I was missing the photos I took around the same time period hers where shot. I didn't have a hardware failure or anything like that, they just weren't there. I do offsite backups but haven't done any since shooting them so they are apparently gone for good. Fortunately they weren't anything important but the concept is SCARY. They are apparently just GONE for no reason.
I'm buying a 320gb drive for one of my other home machines so I can do daily automated backups to that between my offsite backups. Hmmm... come to think of it if I bought another external enclosure I could do my daily backups to that and then swap that with my offsite drive every week.... I guess I have better disaster recovery planning to do.
