In addition to backing up the iOS apps, there are other files, too.
See this: http://support.apple.com/kb/HT5194
or read this:
Note: If you use third-party backup software, make sure that the directory ~/Library/Application Support is not excluded from the backup.
To recover your Apple Configurator data from a Time Machine backup:
- Choose Enter Time Machine from the Time Machine menu extra or System Preference pane.
- Press Command-Shift-G and type: ~/Library/Application Support
- Select the item "com.apple.configurator" in the backup with the appropriate date.
- Click Restore.
If you are using third-party backup software, follow its instructions to restore ~/Library/Application Support/com.apple.configurator.
You may also want to recover the following information from the backup of the same date:
- ~/Library/Keychains, to recover the Supervision Certificate and public and private keys. These will allow supervised devices to reconnect to the host computer.
- ~/Library/Preferences/com.apple.configurator.plist, to restore Configurator settings and preferences.
Restoring data to a new Mac
If you restore the files and folders listed above to a new Mac, you can use it to manage devices supervised by the previous Apple Configurator Mac.
If you have supervised devices with Apple Configurator and you lose the Apple Configurator data files, the devices will still be supervised by the Mac that is running Configurator, but Apple Configurator will not be able to reinstall app backups or user data onto those supervised devices.
It is especially important to back up Apple Configurator information if you are using VPP codes. After a VPP code has been redeemed, only the Apple Configurator database keeps a record of what device that code was redeemed for. If this database is lost, and the app is deleted from the device, Apple Configurator will not be able to reuse the redeemed code in order to install the app, and you will need to purchase and redeem additional codes to replace the app on a device.

I make sure my iPad configurator machine has regular TimeMachine backups. A 500GB USB2 drive is enough to handle the initial startup disk backup & incrementals afterwards. It is important to have a dedicated machine for profile tasks, too. An Intel Core 2 Duo 2GHz or greater Mac Mini should suffice and is quite inexpensive.
