How to back up your iPhone, iPad, and iPod touch -- If restarting your iPhone didn't resolve the issue, please be sure to have a fresh backup to keep your personal information safe.

If you'd like to use iTunes to back up your iPhone, refer to this article: About encrypted backups in iTunes

If the steps above haven't resolved the issue, please answer the following questions:
- Which model of iPhone are you using and which iOS is it currently on?
