Abstract
Archive management is enhanced by logically partitioning a physical cluster. Using an interface, an administrator defines 'tenants' within the cluster. A namespace is a logical partition of the cluster for a collection of objects. Each namespace has a private file system. This approach enables a user to segregate cluster data into logical partitions. Using the interface, a namespace for a tenant is configured without affecting a configuration of another namespace. One configuration option is 'versioning,' by which an administrator can elect to enable multiple versions of a same data object to be stored in association with a namespace. Once versioning is enabled for a namespace, the administrator can set a configuration parameter identifying a time period for maintaining a version. Preferably, versioning is dasabled for a data object under retention.
