I would recommend keeping: 1. A local backup copy on external drives. 2. Backup to crashplan (change settings so if a file is removed locally they keep the copy in the cloud). 3. Burn a copy to DVD (incrementally as they are taken off your cameras/phone) and store those offsite at your parents or a friends house. I usually create DVDs by month for images . . . so you can track down images easier by date and then also have a best of each year on a DVD. Over the years though a lot of photos are taken . . . at some point I expect you'll reach the age where it's physically impossible to even view all the photos you've taken . . . but it will be nice for kids/grand kids in the future to be able to browse through 75 years of grand pa and great grand pa's photos and see what he was up to . . . if the data survives through the generations . . . teach your kids about backups and passing down data . . .
