Cloud Backend
Definition
The vendor-operated server infrastructure where IoT device data is stored, processed, and made accessible via companion apps. The cloud backend is often the richest and longest-retention evidence source, but accessing it requires a legal production order directed at the vendor, who may be in a foreign jurisdiction.

Common questions
Why is the cloud backend often preferred over the device itself for IoT evidence?+
Many IoT devices have limited on-device storage and sync recent activity to the vendor's servers, so the cloud copy can hold a longer history than what remains locally on the device by the time it is seized.
What complicates obtaining IoT cloud backend data in an investigation?+
The vendor may be headquartered in a different country than the investigation, requiring cross-border legal process such as a mutual legal assistance request or an agreement like the CLOUD Act, which adds time and jurisdictional complexity compared to extracting data directly from a seized device.
