Clean up snapshot repository API

Triggers the review of a snapshot repository’s contents and deletes any stale data that is not referenced by existing snapshots.

POST /_snapshot/my_repository/_cleanup

Request

POST /_snapshot/<repository>/_cleanup

Description

Over time, snapshot repositories can accumulate stale data that is no longer referenced by existing snapshots.

While this unreferenced data does not negatively impact the performance or safety of a snapshot repository, it can lead to more storage use than necessary.

You can use the clean up snapshot repository API to detect and delete this unreferenced data.

Most cleanup operations performed by this API are performed automatically when a snapshot is deleted from a repository.

If you regularly delete snapshots, calling this API may only reduce your storage slightly or not at all.

Path parameters

<repository>

(Required, string) Name of the snapshot repository to review and clean up.

Properties of results
