Snapshot of EBS volume created from snapshot

Question

Is next snapshot of new volume incremental or full? For example:  
  
Create a new volume from existing snapshot.  
Create a snapshot from new volume.  
Is this snapshot incremental or full?  
It could be incremental because the volume was derived form a prior snapshot.  
Or it could be full because each new volume creates a new history.  
  
If incremental, then system keeps an incremental history of branches.  
If full, each creation of a new volume from a prior history creates a new, separate history

Answer

Thanks for the quick helpful reply. steve

Answer

Hi,  
  
In short, the first snapshot of each EBS volume is always full and the subsequent snapshots on that same volume are incremental \[1]. I will illustrate this using your own example.  
  
Your question: "Create a new volume from existing snapshot. Create a snapshot from new volume. Is this snapshot incremental or full?"   
Answer: This snapshot is full.
