Never Backing Up Photos

Unless you back up the images on your phone, you're one fumble away from losing them forever. The same goes for shots stored solely on a standalone camera's memory card or a computer, but smartphones are the worst offenders. Since transferring photos can be tedious and user-unfriendly, make backups a scheduled task, setting aside an hour every few months to copy files onto a dedicated hard drive, cloud storage service, or both. It's aggravating, but far less than the alternative.
