OptionalincludeWhen true, returns backups from every index in the project that has ever
used this name, including deleted ones. Backups from a deleted index carry a
sourceIndexDeletedAt timestamp.
When false or omitted, indexName must resolve to an active index; if only
deleted indexes have used the name, the API returns a 404 rather than an
empty list.
OptionalindexOmit to list all project backups.
OptionallimitMaximum number of results per page. Omit to use the service default.
OptionalpaginationPagination token from a prior response to retrieve the next page.
