Get snapshot status
Introduced 1.0
Returns details about a snapshot’s state during and after snapshot creation.
To learn about snapshot creation, see Create snapshot.
If you use the Security plugin, you must have the monitor_snapshot, create_snapshot, or manage cluster privileges.
Path parameters
Path parameters are optional.
| Parameter | Data type | Description |
|---|---|---|
| repository | String | The repository containing the snapshot. |
| snapshot | List | The snapshot(s) to return. |
| index | List | The indexes to include in the response. |
Three request variants provide flexibility:
-
GET _snapshot/_statusreturns the status of all currently running snapshots in all repositories. -
GET _snapshot/<repository>/_statusreturns all currently running snapshots in the specified repository. This is the preferred variant. -
GET _snapshot/<repository>/<snapshot>/_statusreturns detailed status information for a specific snapshot(s) in the specified repository, regardless of whether it’s currently running. -
GET /_snapshot/<repository>/<snapshot>/<index>/_statusreturns detailed status information only for the specified indexes in a specific snapshot in the specified repository. Note that this endpoint works only for indexes belonging to a specific snapshot.
Snapshot API calls only work if the total number of shards across the requested resources, such as snapshots and indexes created from snapshots, is smaller than the limit specified by the following cluster setting:
snapshot.max_shards_allowed_in_status_api(Dynamic, integer): The maximum number of shards that can be included in the Snapshot Status API response. Default value is200000. Not applicable for shallow snapshots v2, where the total number and sizes of files are returned as 0.
Using the API to return the state of snapshots that are not currently running can be very costly in terms of both machine resources and processing time when querying data in the cloud. For each snapshot, each request causes a file read of all of the snapshot’s shards.
Request fields
| Field | Data type | Description |
|---|---|---|
| ignore_unavailable | Boolean | How to handle requests for unavailable snapshots and indexes. If false, the request returns an error for unavailable snapshots and indexes. If true, the request ignores unavailable snapshots and indexes, such as those that are corrupted or temporarily cannot be returned. Default is false. |
Example request
The following request returns the status of my-first-snapshot in the my-opensearch-repo repository. Unavailable snapshots are ignored.
GET _snapshot/my-opensearch-repo/my-first-snapshot/_status
{
"ignore_unavailable": true
}
Example response
The example that follows corresponds to the request above in the Example request section.
The GET _snapshot/my-opensearch-repo/my-first-snapshot/_status request returns the following fields:

| State | Description |
|---|---|
| FAILED | The snapshot terminated in an error and no data was stored. |
| IN_PROGRESS | The snapshot is currently running. |
| PARTIAL | The global cluster state was stored, but data from at least one shard was not stored. The failures property of the Create snapshot response contains additional details. |
| SUCCESS | The snapshot finished and all shards were stored successfully. |

| total | Total number of shards included in the snapshot. |
Snapshot file stats
| Property | Type | Description |

| processed | Object | Number and size of files already uploaded to the snapshot. The processed file_count and size_in_bytes are incremented in stats after a file is uploaded. |
| total | Object | Total number and size of files that are referenced by the snapshot. |
| start_time_in_millis | Long | Time (in milliseconds) when snapshot creation began. |
| time_in_millis | Long | Total time (in milliseconds) that the snapshot took to complete. |
Index objects
| Property | Type | Description |
|---|---|---|
| shards_stats | Object | See Shard stats. |
| stats | Object | See Snapshot file stats. |
| shards | List of objects | Contains information about the shards included in the snapshot. OpenSearch returns the following properties about the shard: stage: The current state of shards in the snapshot. Shard states are: * DONE: The number of shards in the snapshot that were successfully stored in the repository. * FAILURE: The number of shards in the snapshot that were not successfully stored in the repository. * FINALIZE: The number of shards in the snapshot that are in the finalizing stage of being stored in the repository. * INIT: The number of shards in the snapshot that are in the initializing stage of being stored in the repository. * STARTED: The number of shards in the snapshot that are in the started stage of being stored in the repository. stats: See Snapshot file stats. total: The total number and sizes of files referenced by the snapshot. start_time_in_millis: The time (in milliseconds) when snapshot creation began. time_in_millis: The total amount of time (in milliseconds) that the snapshot took to complete. |
