# Replicas
```yaml
action: replicas
description: >- Set the number of replicas per shard for selected
    indices to 'count'
options:
  count: ...
filters:
- filtertype: ...
```

<note>
  Empty values and commented lines will result in the default value, if any, being selected.  If a setting is set, but not used by a given action, it will be ignored.

This action will set the number of replicas per shard to the value of [count](https://www.elastic.co/elastic/docs-builder/docs/3028/reference/elasticsearch/curator/option_count).
You can optionally set `wait_for_completion` to `True` to have Curator wait for the replication operation to complete before continuing:
```yaml
action: replicas
description: >- Set the number of replicas per shard for selected
    indices to 'count'
options:
  count: ...
  wait_for_completion: True
  max_wait: 600
  wait_interval: 10
filters:
- filtertype: ...
```

This configuration will wait for a maximum of 600 seconds for all index replicas to be complete before giving up.  A `max_wait` value of `-1` will wait indefinitely.  Curator will poll for completion at `10` second intervals, as defined by `wait_interval`.
