Execute snapshot lifecycle policy API

edit

Execute snapshot lifecycle policy API

edit

Executes a snapshot lifecycle policy, immediately creating a snapshot without waiting for the scheduled creation time.

Request

edit

PUT /_slm/policy/<snapshot-lifecycle-policy-id>/_execute

Description

edit

Sometimes it can be useful to immediately execute a snapshot based on policy, perhaps before an upgrade or before performing other maintenance on indices. The execute snapshot policy API allows you to perform a snapshot immediately without waiting for a policy’s scheduled invocation.

Path parameters

edit
<snapshot-lifecycle-policy-id>
(Required, string) ID of the snapshot lifecycle policy to execute.

Examples

edit

To take an immediate snapshot using a policy, use the following request:

PUT /_slm/policy/daily-snapshots/_execute

This API returns the following response with the generated snapshot name:

{
  "snapshot_name": "daily-snap-2019.04.24-gwrqoo2xtea3q57vvg0uea"
}

The snapshot will be taken in the background, you can use the snapshot APIs to monitor the status of the snapshot.

Once a snapshot has been kicked off, you can see the latest successful or failed snapshot using the get snapshot lifecycle policy API:

GET /_slm/policy/daily-snapshots?human

Which, in this case shows an error because the index did not exist:

{
  "daily-snapshots" : {
    "version": 1,

The last unsuccessfully initiated snapshot by this policy, along with the details of its failure

In this case, it failed due to the "important" index not existing and ignore_unavailable setting being set to false.

Updating the policy to change the ignore_unavailable setting is done using the same put snapshot lifecycle policy API:

PUT /_slm/policy/daily-snapshots
{
  "schedule": "0 30 1 * * ?",
  "name": "<daily-snap-{now/d}>",
  "repository": "my_repository",
  "config": {
    "indices": ["data-*", "important"],
    "ignore_unavailable": true,
    "include_global_state": false
  }
}

Another snapshot can immediately be executed to ensure the new policy works:

PUT /_slm/policy/daily-snapshots/_execute
{
  "snapshot_name": "daily-snap-2019.04.24-tmtnyjtrsxkhbrrdcgg18a"
}

Now retrieving the policy shows that the policy has successfully been executed:

GET /_slm/policy/daily-snapshots?human

Which now includes the successful snapshot information:

{
  "daily-snapshots" : {
    "version": 2, 
    "modified_date": "2019-04-23T01:30:00.000Z",

      "schedule": "0 30 1 * * ?",
      "name": "<daily-snap-{now/d}>",
      "repository": "my_repository",
      "config": {
        "indices": ["data-*", "important"],
        "ignore_unavailable": true,
        "include_global_state": false
      }
    },

    } ,
    "next_execution": "2019-04-24T01:30:00.000Z",
    "next_execution_millis": 1556048160000
  }
}

The policy’s version has been incremented because it was updated

The last successfully initiated snapshot information

It is a good idea to test policies using the execute API to ensure they work.
