Recommendation to Backup Configuration

I had an obi110 for two years. The phone port drives the lines in my house. After a thunderstorm passed by today, the phone port failed. Everything else about the obi works. I can access through the browser or the web site and I can make a call with my tablet through the obi using Csipsimple. This is a strange failure since no other device on my network has failed and there have been other thunderstorms since I started using the obi. Anyway, everyone knows they should back up their computer but I bet few think about backing up their obi unit. Fortunately only the phone port failed and I was able to backup the configuration which means I can import the backup into a new unit I ordered.
