The feature which will act exactly the same for snapshot like is at the moment for backup would be perfect.
I can imagine a scenario that the gateway (or management) will check available disk space for the creation of snapshot, create snapshot itself, export snapshot, move it to the desired location outside of the box, delete exported snapshot from the gateway (or management) and finally remove snapshot partition created during creation.
Consider it as a suggestion for RFE 🙂
