default Get Snapshot Status Snapshot APIs 8

Get snapshot status

Returns details about a snapshots 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. {: .note}

Path parameters

Path parameters are optional.

Parameter Data type Description
repository String Repository containing the snapshot.
snapshot String Snapshot to return.

Three request variants provide flexibility:

  • GET _snapshot/_status returns the status of all currently running snapshots in all repositories.

  • GET _snapshot/<repository>/_status returns the status of only currently running snapshots in the specified repository. This is the preferred variant.

  • GET _snapshot/<repository>/<snapshot>/_status returns the status of all snapshots in the specified repository whether they are running or not.

Using the API to return state for other than currently running snapshots can be very costly for (1) machine machine resources and (2) processing time if running in the cloud. For each snapshot, each request causes file reads from all a snapshot's shards. {: .warning}

Request fields

Field Data type Description
ignore_unavailable Boolean How to handles requests for unavailable snapshots. If false, the request returns an error for unavailable snapshots. If true, the request ignores unavailable snapshots, such as those that are corrupted or temporarily cannot be returned. Defaults to false.

Sample 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 
}

{% include copy-curl.html %}

Sample response

The example that follows corresponds to the request above in the Sample request section.

The GET _snapshot/my-opensearch-repo/my-first-snapshot/_status request returns the following fields:

Response fields

Field Data type Description
repository String Name of repository that contains the snapshot.
snapshot String Snapshot name.
uuid String Snapshot Universally unique identifier (UUID).
state String Snapshot's current status. See Snapshot states.
include_global_state Boolean Whether the current cluster state is included in the snapshot.
shards_stats Object Snapshot's shard counts. See Shard stats.
stats Object Details of files included in the snapshot. file_count: number of files. size_in_bytes: total of all fie sizes. See Snapshot file stats.
index list of Objects List of objects that contain information about the indices in the snapshot. See Index objects.
Snapshot states
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.
Shard stats

All property values are Integers.

Property Description
initializing Number of shards that are still initializing.
started Number of shards that have started but not are not finalized.
finalizing Number of shards that are finalizing but are not done.
done Number of shards that initialized, started, and finalized successfully.
failed Number of shards that failed to be included in the snapshot.
total Total number of shards included in the snapshot.
Snapshot file stats
Property Type Description
incremental Object Number and size of files that still need to be copied during snapshot creation. For completed snapshots, incremental provides the number and size of files that were not already in the repository and were copied as part of the incremental snapshot.
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 List of objects containing information about the shards that include the snapshot. Properies of the shards are listed below in bold text.

stage: Current state of shards in the snapshot. Shard states are:

* DONE: Number of shards in the snapshot that were successfully stored in the repository.

* FAILURE: Number of shards in the snapshot that were not successfully stored in the repository.

* FINALIZE: Number of shards in the snapshot that are in the finalizing stage of being stored in the repository.

* INIT: Number of shards in the snapshot that are in the initializing stage of being stored in the repository.

* STARTED: Number of shards in the snapshot that are in the started stage of being stored in the repository.

stats: See Snapshot file stats.

total: Total number and size of files referenced by the snapshot.

start_time_in_millis: Time (in milliseconds) when snapshot creation began.

time_in_millis: Total time (in milliseconds) that the snapshot took to complete.
