Get data distribution

GET /data/{id}/distribution

Returns information about distribution of a specific file among different storage providers. Symbolic links are not supported, since data distribution is not applicable for them. The locationsPerStorageBackend field is the same as for the Get file storage locations endpoint.

Example cURL requests

Get file distribution

curl -H "X-Auth-Token: $TOKEN" -X GET "https://$PROVIDER_HOST/api/v3/oneprovider/data/$FILE_ID/distribution"
