Curator does not backup all index on Azure

[RdrgPorto (Rodrigo Porto)]

Hi, everyone

I use Curator tool in order to backup all my index on Azure. However, it only backup 46 index.

On Kibana:

PUT _snapshot/azure
{
  "type": "azure",
  "settings": {
    "container": "container-name-azure",
    "compress" : true
  }
}

On Curator:

    ---
    actions:
      1:
        action: delete_snapshots
        description: >-
          Delete daily snapshot
        options:
            repository: azure
            ignore_empty_list: True
            retry_interval: 120
            retry_count: 3
            disable_action: False
        filters:
        - filtertype: pattern
          kind: regex
          value: '^(full-daily-)'
        - filtertype: age
          source: name
          direction: older
          timestring: '%Y.%m.%d'
          unit: days
          unit_count: 7
      2:
        action: snapshot
        description: >-
          Daily snapshot of everything
        options:
            repository: azure
            name: full-daily-%Y.%m.%d
            ignore_empty_list: True
            ignore_unavailable: False
            include_global_state: True
            partial: False
            wait_for_completion: True
            skip_repo_fs_check: False
            disable_action: False
        filters:
        - filtertype: closed
          exclude: True

It is due to Azure or Curator has a limit ? Where is the error ?

Thanks in advance,

Regards

Update

It was due to ILM:

allow_ilm_indices: True
