G06F 17/30

US Classification:

707692, 707E17007

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.

US Classification:

710 15

Abstract:

Provided are techniques for storing one or more storage rules for each of one or more storage locations, along with one or more actions to be taken for each storage rule that is violated, intercepting an I/O operation issued to the storage subsystem, and determining whether the I/O operation violates one or more of the storage rules. In response to determining that the I/O operation violates one or more of the storage rules, an application that issued the I/O operation is identified and each of the one or more actions associated with the one or more violated storage rules are performed.
