iOS Backup files include device settings from the Settings app, home and lock screen images, icon arrangement and app content and settings. Backups do NOT contain apps or iTunes media.
GroundControl allows you to restore a single backup to many devices. In this way, you can control settings that aren’t available to MDM or DEP. For example, using a backup you can set the following:
|Feature||iOS 10||iOS 11||Notes|
|Airplane Mode on/off|
|WiFi on/off||Useful if Airplane mode is on|
|Bluetooth on/off||(May require similar devices for master & clone)|
|AMBER and Weather Alerts|
|Do Not Disturb|
|Brightness Level||Auto Brightness was removed in iOS 11|
|Raise to Wake|
|Automatically lock after...|
|Passcode Required After...|
|Battery Percentage on/off|
|Location Services on/off||Settings > General > Privacy > Location Services|
|Apple ID (iTunes Store)||GroundControl's "Backup Scrubbing" must be disabled|
|Accessibility: Large Text, Reduce Motion, Assistive Touch|
|Background App Refresh|
|Enterprise App Trust||Useful if you don't have MDM|
|Contacts||Contact list is preserved from master to slave|
Some settings are never preserved within backups.
- You can not save a device passcode
- You can not grant permissions for camera or microphone for specific apps
When creating your master backup, remember that any settings will be duplicated to all your devices. Try to avoid adding an Apple ID on the master. Also we recommend starting with an erased device each time, to be sure you don’t have any undesired settings.
GroundControl helps you by automatically “scrubbing” the backup to remove Apple ID, MDM, saved WiFi networks, and supervision. GroundControl also “depersonalizes” the backup so that a common backup may be used across any iOS device type, and nearly any iOS version.
Follow the instructions below to create your back up, compress it and upload it to GroundControl.
Step 4: Compress the Backup for use with GroundControl
The backup folder is named with the device’s UDID. You can sort by date and time, and find the most recent folder.
We need to compress these backups files before we can upload them to GroundControl.
- Open the folder in order to display the list of folders within
- Select all folders inside the folder as shown in the image above. Important: do not select the backup folder itself, only the folders contained within.
- On Windows, right-click and send to “Compressed (zipped) folder”. On Mac, control-click and choose “Compress”.
- A zip file will be created, e.g. “Archive.zip”.
- Rename the zip file as desired. You may keep the .ZIP extension, or rename it to the traditional .iosdevicebackup.
- Move the file to another location, such as your Desktop.
The backup is now ready to be uploaded to GroundControl.
You’re done! You should now quit iTunes (or Configurator), upload your image to GroundControl and test the restore.
Tip: Test on a different device from your master. The mastering process may require a few more trips to the master device to tweak your settings, and the process will be easier if you keep your master around.
