edit

Use the put snapshot lifecycle policy API to create or update a snapshot lifecycle policy.

If the policy already exists, this request increments the policy’s version. Only the latest version of the policy is stored.

Path parameters

edit
<snapshot-lifecycle-policy-id>
(Required, string) ID for the snapshot lifecycle policy you want to create or update.

Query parameters

edit
timeout
(Optional, time units) Specifies the period of time to wait for a response. If no response is received before the timeout expires, the request fails and returns an error. Defaults to 30s.
master_timeout
(Optional, time units) Specifies the period of time to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error. Defaults to 30s.

Request body

edit
schedule

(Required, Cron scheduler configuration) Periodic or absolute schedule at which the policy creates snapshots and deletes expired snapshots.

Schedule changes to existing policies are applied immediately.

This value supports the same date math supported in index names.

To prevent conflicting snapshot names, a UUID is automatically appended to each snapshot name.

repository

(Required, string) Repository used to store snapshots created by this policy.

This repository must exist prior to the policy’s creation. You can create a repository using the snapshot repository API.

config

(Required, object) Configuration for each snapshot created by the policy.

Parameters include:

indices
(Optional, array of strings) Array of index names or wildcard pattern of index names included in snapshots.
ignore_unavailable
(Optional, boolean) If true, missing indices do not cause snapshot creation to fail and return an error. Defaults to false.
include_global_state
(Optional, boolean) If true, cluster states are included in snapshots. Defaults to false.

Examples
