Abstract: A system includes a data storage device for storing storage volumes, logic adapted for associating an indicator with a data set on the storage volumes, the indicator being in a first state indicating that the data set is accessible, logic adapted for storing the indicator in a data set descriptor record that is stored in at least one mapping of the storage volumes, logic adapted for receiving a request to delete the data set, logic adapted for changing the indicator to a second state indicating that the data set is inaccessible in response to the request to delete the data set, with the proviso that the data set is unchanged, logic adapted for receiving a request to restore the deleted data set, and logic adapted for restoring the indicator from the second state to the first state in response to the request to restore the deleted data set.

Abstract: In one embodiment, a system includes a data storage device for storing one or more storage volumes, logic adapted for associating an indicator with a data set on the one or more storage volumes, wherein the indicator is in a first state indicating that the data set is accessible, logic adapted for storing the indicator associated with the data set in a data set descriptor record, wherein the record is stored in at least one mapping of the one or more storage volumes, logic adapted for receiving a request to delete the data set, logic adapted for changing the indicator to a second state indicating that the data set is inaccessible in response to the request to delete the data set, with the proviso that the data set is unchanged, logic adapted for receiving a request to restore the deleted data set, and logic adapted for restoring the indicator from the second state to the first state in response to the request to restore the deleted data set.
