If you use an iPad, iPhone or Mac computer, you must be backing up at least weekly, and preferably daily. If it’s possible, make multiple backups in different places.
Keep Duplicates
For cheap devices, or those which only last a year or less, keep duplicates available as much as possible. Things that might come into this category depends on your assistive technology needs and how rough you are on your devices, but some examples would be:
- Styluses
- Mouth sticks and head pointers
- Switches
- Headphones, earbuds, or headsets
- Trackpads and mice
- Cables for charging iPhones and iPads
