Fix Recommendation

Install a configuration profile to disable backup of managed apps.

Must be configured on the MDM server for each managed app.

Check Contents

Review configuration settings to confirm backup in management apps is disabled and "Encrypt local backup" is enabled in iTunes (for Windows computer) and in Finder on Mac.

Note: iTunes Backup/Finder backup is implemented by the configuration policy rule "Force encrypted backups", which is included in AIOS-26-010700 and therefore, not included in the procedure below.

This check procedure is performed on both the Apple iOS/iPadOS management tool and the iPhone and iPad.

Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review.

In the Apple iOS/iPadOS management tool, verify backing up app data is disabled.

On the iPhone and iPad:
1. Open the Settings app.
2. Tap "General".
3. Tap "VPN & Device Management".
4. Tap the Configuration Profile from the Apple iOS/iPadOS management tool containing the restrictions policy.
5. Tap "Apps".
6. Tap a managed app.
7. Verify "App data will not be backed up" is listed.

Note: Steps 6 and 7 must be performed for each managed app.

If backing up app data is not disabled in the Apple iOS/iPadOS management tool or "app data will not be backed up" is not listed for each managed app on the iPhone and iPad, this is a finding.
