Metadata protection

Object metadata is information related to or a description of an object; for example, object modification time, or storage location. StorageGRID Webscale stores object metadata in a Cassandra database, which interfaces with the DDS service.

To ensure redundancy and thus protection against loss, three copies of object metadata are maintained. The copies are load balanced across all Storage Nodes at each site. This replication is non-configurable and performed automatically.
