cat snapshots API

edit

cat APIs are only intended for human consumption using the command line or Kibana console. They are not intended for use by applications. For application consumption, use the get snapshot API.

Returns information about the snapshots stored in one or more repositories. A snapshot is a backup of an index or running Elasticsearch cluster.

Request

edit

GET /_cat/snapshots/<repository>

GET /_cat/snapshots

Prerequisites

edit

If the Elasticsearch security features are enabled, you must have the monitor_snapshot, create_snapshot, or manage cluster privilege to use this API.

Path parameters

edit

<repository>

(Optional, string) Comma-separated list of snapshot repositories used to limit the request. Accepts wildcard expressions. _all returns all repositories.

If any repository fails during the request, Elasticsearch returns an error.

Query parameters

edit

If you do not specify which columns to include, the API returns the default columns in the order listed below. If you explicitly specify one or more columns, it only returns the specified columns.

Valid columns are:

id, snapshot

(Default) ID of the snapshot, such as snap1.

repository, re, repo

(Default) Name of the repository, such as repo1.

status, s

(Default) State of the snapshot process. Returned values are:

FAILED: The snapshot process failed.
INCOMPATIBLE: The snapshot process is incompatible with the current cluster version.
IN_PROGRESS: The snapshot process started but has not completed.
PARTIAL: The snapshot process completed with a partial success.
SUCCESS: The snapshot process completed with a full success.

start_epoch, ste, startEpoch

(Default) Unix epoch time at which the snapshot process started.

start_time, sti, startTime

(Default) HH:MM:SS time at which the snapshot process started.

end_epoch, ete, endEpoch

(Default) Unix epoch time at which the snapshot process ended.

end_time, eti, endTime

(Default) HH:MM:SS time at which the snapshot process ended.

duration, dur

(Default) Time it took the snapshot process to complete in time units.

indices, i

(Default) Number of indices in the snapshot.

successful_shards, ss

(Default) Number of successful shards in the snapshot.

failed_shards, fs

(Default) Number of failed shards in the snapshot.

total_shards, ts

ignore_unavailable

(Optional, Boolean) If true, the response does not include information from unavailable snapshots. Defaults to false.
