If you have selected "Backup to the iCloud" in iTunes, iCloud will automatically back up your Property Inspection BOSS data (as well as all your other apps data and photos etc) daily over Wi-Fi when your device is connected to a power source. Once you plug it in, everything is backed up quickly and efficiently. 

More information about this iPad feature can be obtained from Apple Support/iCloud Overview
