Abstract:
1. A system for hiding information related to a component of a file system in a persistent image, the component having an associated component identifier, the system comprising: a processor coupled to a memory, the memory storing a data set, wherein the data set is operable as an exclusion list or an inclusion list in which a component identifier and a persistent image identifier in the data set identify a component of a persistent image that is obscured from or visible to access requests for the persistent image, wherein the persistent image represents a previous state of data in the file system at a previous time, wherein a current state of the data in the file system is different than the previous state of data in the file system; a lookup mechanism executed by the processor, the lookup mechanism operable to access the persistent image and obtain the information related to the component as it existed as of the previous time; the data set being functionally coupled between the lookup mechanism and the persistent image, wherein the lookup mechanism is operable to, responsive to an access request from a user or application program involving the data of the persistent image, check the data set to determine if the component identifier for the component of the persistent image is in the data set; and the lookup mechanism being operable to hide or make available the information related to the component of the persistent image if the component identifier is in the exclusion list or inclusion list.
