To learn more about static and dynamic settings, see [Configuring OpenSearch]({{site.url}}{{site.baseurl}}/install-and-configure/configuring-opensearch/index/).
## Snapshot settings
OpenSearch supports the following snapshot settings:
-`snapshot.max_concurrent_operations`(Dynamic, integer): The maximum number of concurrent snapshot operations. Default is `1000`.
### Security-related snapshot settings
For security-related snapshot settings, see [Security settings]({{site.url}}{{site.baseurl}}/install-and-configure/configuring-opensearch/security-settings/).
For information about file system settings, see [Shared file system]({{site.url}}{{site.baseurl}}/tuning-your-cluster/availability-and-recovery/snapshots/snapshot-restore/#shared-file-system).

## Cluster manager task throttling settings
For information about cluster manager task throttling settings, see [Setting throttling limits]({{site.url}}{{site.baseurl}}/tuning-your-cluster/cluster-manager-task-throttling/#setting-throttling-limits).
## Remote-backed storage settings
OpenSearch supports the following cluster-level remote-backed storage settings:
-`cluster.remote_store.translog.buffer_interval` (Dynamic, time unit): The default value of the translog buffer interval used when performing periodic translog updates. This setting is only effective when the index setting `index.remote_store.translog.buffer_interval` is not present.
-`remote_store.moving_average_window_size` (Dynamic, integer): The moving average window size used to calculate the rolling statistic values exposed through the [Remote Store Stats API]({{site.url}}{{site.baseurl}}/tuning-your-cluster/availability-and-recovery/remote-store/remote-store-stats-api/). Default is `20`. Minimum enforced is `5`.
For more remote-backed storage settings, see [Remote-backed storage]({{site.url}}{{site.baseurl}}/tuning-your-cluster/availability-and-recovery/remote-store/index/) and [Configuring remote-backed storage]({{site.url}}{{site.baseurl}}/tuning-your-cluster/availability-and-recovery/remote-store/index/#configuring-remote-backed-storage).

## Search backpressure settings
Search backpressure is a mechanism used to identify resource-intensive search requests and cancel them when the node is under duress. For more information, see [Search backpressure settings]({{site.url}}{{site.baseurl}}/tuning-your-cluster/availability-and-recovery/search-backpressure/#search-backpressure-settings).
## Shard indexing backpressure settings
Shard indexing backpressure is a smart rejection mechanism at a per-shard level that dynamically rejects indexing requests when your cluster is under strain. For more information, see shard indexing backpressure [settings]({{site.url}}{{site.baseurl}}/tuning-your-cluster/availability-and-recovery/shard-indexing-settings/).
