Points well taken. ALL my stuff, except music and video, are 3 copies everyday. I used my tablet in work, and immediately enterring data, I saved to the int media, then to the ext media, then "shared folder" to my PC. The majority of the card will be for music/video which are copies from my PC. Your point is a good point and should be reminded as often as possible. I also remember a similar warning form an IT collegeau when harddisk FIRST came out, "hard disk provides a false security, always back up" bun
In 1956 IBM invented the first computer disk storage system, the 305 RAMAC (Random Access Method of Accounting and Control). This system could store five MBytes. It had fifty, 24-inch diameter disks!
