I'm looking for a solution to backing up photos (shot in raw on 6D) while on trips. I'm tired of lugging around my laptop, and have only been carrying an iPad with me. I've tried researching ways to upload to my iPad, then upload the raw files to a cloud of some type. I've not had any luck finding a way to make this happen. I've decided it would be easier if I had a hard drive that I can plug my SD card into and backup the photos that way. Has anyone had success with a photo backup drive of this type? I'ver researched a few and have not read any good reviews on them. Hoping the members of this site can help me out some.
