An object's life consists of various stages. The stages represent the operations that occur with the object. Information lifecycle management (ILM) rules affect how objects are managed during each of these stages. The term object management refers to how an object is stored over time and protected from loss.
The life of an object includes the operations of ingest, retrieve, delete, and archive.
- Ingest: The process of a client application saving an object over HTTP to the StorageGRID Webscale system. At this stage, the StorageGRID Webscale system begins to manage the object.
- Retrieve: The process of a client application accessing an object stored by the StorageGRID Webscale system. The client reads the object, which is retrieved from a Storage Node or Archive Node over HTTP.
- Delete: The process of the client application sending a delete request to the StorageGRID Webscale system, which in turn sends an HTTP removal command to all object locations.
- Archive: If the Information Lifecycle Management (ILM) policy requires archival, a copy of the object data is made and saved to the archival storage system.
