Help Need a fresh start - How to backup the phone

[jfe]

OK, I've had my GNEX since it was first released, and I've ammassed 1,600+ photos in the device

Needless to say, it takes a while to load the camera, gallery, and anything associated with it

I think it's time to give this guys a good factory wipe, and no, I am not rooted, and can't have one of those nifty apps that get all the data

I've backed up all my photos to Dropbox, contacts, emails, calendar are never a problem.

And most the apps I use nothing is stored in the phone, they are all central accounts like evernote and the such

Before wiping the phone, any recommendations?

I am really not in to the rooting business anymore, I did that extensively with my OG Droid, but this one I've found no need.

Any suggestions?

Thanks
