Get a small flash drive, put your backup and latest firmware upgrade on it from your kemper. Now put some velcro on it and the inside edge of your Kemper on the back.
Now if you ever need to, you can restore your kemper at a gig. Or if you are at home doing an update, you know where that damned flash drive is. One thing I rarely hear about is how easy it is to upgrade with a flash drive... it's cheap insurance for sure. Oh, and make a backup of your files on your PC too.
