KNOX-07-004950 - The Samsung must be configured to not allow backup to remote systems: Disable Allow Google Accounts Auto Sync.

Information

Backups to remote systems (including cloud backup) can leave data vulnerable to breach on the external systems, which often offer less protection than the Samsung Android 7 with Knox. Where the remote backup involves a cloud-based solution, the backup capability is often used to synchronize data across multiple devices. In this case, DoD devices may synchronize DoD-sensitive information to a user's personal device or other unauthorized computers that are vulnerable to breach. Disallowing remote backup mitigates this risk.
