If you have access to a computer you can copy and save SD Cards to named files either on the computer itself or to a PORTABLE HARDRIVE which in an emergency can be copied to a new SD Card. Luckily I've been able to do that since I took delivery of my KN7000. For this purpose, I have a portable 2-Terrabytes "Hitachi Life Studio" hardrive which has all my SD Cards, Floppies, mini disks and my own CDs saved to it complete with their song/music titles. For the safekeeping of my private files, I use a Freecom 400GB Portable Hardrive which also houses my current music gig. Of course the Portable HDs are a little expensive to buy but I've never regretted it, particularly when I lost one of my gig SD cards a few years ago and was able to retrieve it immediately.

I hope this may help in some way - Audrey Turner
