Using 2 iPads at a gig. One backing up the other

[cfautley]

I've resorted to using 2 iPads at gigs. One for setlistmaker and the other as my iem mix app. This allows me to easily adjust my iem without flipping screens on 1 iPad.
I use the midi Bluetooth on SLM to set my pedal board patches and to play certain backing tracks when doing some duo stuff.
So, I have the perfect opportunity for one iPad to backup the other for SLM. However, how do I do this without having to export and import every change?
Appreciate any help
