Curator snapshot rotation

Thank you for the response......

what exactly i need is to create snapshots automatically at some interval as well as delete older snapshots keeping a duplicate copy of older snapshots at so and so path

so that i created one yaml file with two actions one is creating snapshot the other action is deleting older snapshots and i run that yaml file in cronjob so that it can perform both the actions automatically

here is the yaml file...

actions:
  1:
    action: snapshot
    description: >-
      Snapshot logstash- prefixed indices older than 1 day (based on index
      creation_date) with the default snapshot name pattern of
      'curator-%Y%m%d%H%M%S'.  Wait for the snapshot to complete.  Do not skip
      the repository filesystem access check.  Use the other options to create
      the snapshot.
    options:
      repository: databackup
      name:
      ignore_unavailable: False
      include_global_state: True
      partial: False
      wait_for_completion: True
      skip_repo_fs_check: False
      disable_action: false
    filters:
    - filtertype: pattern
      kind: prefix
      value: twitter
    - filtertype: age
      source: creation_date
      direction: older
      unit: days
      unit_count: 1
  2:
    action: delete_snapshots
    description: >-
      Delete snapshots from the selected repository older than 30 seconds
      (based on creation_date), for 'curator-' prefixed snapshots.
    options:
      repository: databackup
      retry_interval: 30
      retry_count: 2
disable_action: false
    filters:
    - filtertype: pattern
      kind: prefix
      value: curator-
      exclude:
    - filtertype: age
      source: creation_date
      direction: older
      unit: seconds
      unit_count: 50

but i dont want to follow cronjob to create and delete snapshots automatically

please suggest any other option in curator to do that job without cronjob.

Thanks in Advance.
