How to back up DSLR pictures with Android? I'm going to be traveling soon and taking a DSLR camera and Galaxy S5 mobile phone. How could I transfer the pictures to my phone and then to a backup service such as DropBox or Google Drive? I anticipate taking more than 100 GB of pictures.
Wi-fi memory cards! That is, if your camera doesn't have Wi-fi capability itself.

  Eye-Fi and Transcend wireless cards can both connect to a smartphone or tablet, providing the ability to wirelessly transfer images and videos to the device.
