Create snapshot API

edit

Create snapshot API

edit

Takes a snapshot of a cluster or specified data streams and indices.

response = client.snapshot.create(
  repository: 'my_repository',
  snapshot: 'my_snapshot'
)
puts response
PUT /_snapshot/my_repository/my_snapshot

Request

edit

PUT /_snapshot/<repository>/<snapshot>

POST /_snapshot/<repository>/<snapshot>

Prerequisites

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

Path parameters

edit
<repository>
(Required, string) Name of the snapshot repository.
<snapshot>
(Required, string) Name of the snapshot. Supports date math. Must be unique within the snapshot repository.

Query parameters

edit
master_timeout
(Optional, time units) Period to wait for the master node. If the master node is not available before the timeout expires, the request fails and returns an error. Defaults to 30s. Can also be set to -1 to indicate that the request should never timeout.
wait_for_completion
(Optional, Boolean) If true, the request returns a response when the snapshot is complete. If false, the request returns a response when the snapshot initializes. Defaults to false.

Request body

edit
expand_wildcards

(Optional, string) Determines how wildcard patterns in the indices parameter match data streams and indices. Supports comma-separated values, such as open,hidden. Defaults to all. Valid values are:

all
Match any data stream or index, including closed and hidden ones.
open
Match open indices and data streams.
closed
Match closed indices and data streams.
hidden
Match hidden data streams and indices. Must be combined with open, closed, or both.
none
Don’t expand wildcard patterns.
ignore_unavailable
(Optional, Boolean) If false, the snapshot fails if any data stream or index in indices is missing. If true, the snapshot ignores missing data streams and indices. Defaults to false.
include_global_state

(Optional, Boolean) If true, include the cluster state in the snapshot. Defaults to true. The cluster state includes:

indices

(Optional, string or array of strings) Comma-separated list of data streams and indices to include in the snapshot. Supports multi-target syntax. Defaults to an empty array ([]), which includes all regular data streams and regular indices. To exclude all data streams and indices, use -*.

You can’t use this parameter to include or exclude system indices or system data streams from a snapshot. Use feature_states instead.

feature_states

(Optional, array of strings) Feature states to include in the snapshot. To get a list of possible values and their descriptions, use the get features API.

If include_global_state is true, the snapshot includes all feature states by default. If include_global_state is false, the snapshot includes no feature states by default.

Note that specifying an empty array will result in the default behavior. To exclude all feature states, regardless of the include_global_state value, specify an array with only the value none (["none"]).

metadata
(Optional, object) Attaches arbitrary metadata to the snapshot, such as a record of who took the snapshot, why it was taken, or any other useful data. Metadata must be less than 1024 bytes.
partial

(Optional, Boolean) If false, the entire snapshot will fail if one or more indices included in the snapshot do not have all primary shards available. Defaults to false.

If true, allows taking a partial snapshot of indices with unavailable shards.

Examples

edit

The following request takes a snapshot of index_1 and index_2.

response = client.snapshot.create(
  repository: 'my_repository',
  snapshot: 'snapshot_2',
  wait_for_completion: true,
  body: {
    indices: 'index_1,index_2',
    ignore_unavailable: true,
    include_global_state: false,
    metadata: {
      taken_by: 'user123',
      taken_because: 'backup before upgrading'
    }
  }
)
puts response
PUT /_snapshot/my_repository/snapshot_2?wait_for_completion=true
{
  "indices": "index_1,index_2",
  "ignore_unavailable": true,
  "include_global_state": false,
  "metadata": {
    "taken_by": "user123",
    "taken_because": "backup before upgrading"
  }
}

The API returns the following response:
