What is difference between indices snapshot and cluster snapshot?

[163satish (163)]

I am working on the curator snapshot and restore feature. Can you please elaborate on how these 2 are different?
I have used following template to take snapshot:

action: snapshot
description: >-
  Snapshot selected indices to 'repository' with the snapshot name or name
  pattern in 'name'.  Use all other options as assigned
options:
  repository: ...
  # Leaving name blank will result in the default 'curator-%Y%m%d%H%M%S'
  name:
  wait_for_completion: True
  max_wait: 3600
  wait_interval: 10
filters:
- filtertype: ...

Let me know how to differentiate based on this template.
