Technique for remapping data in a storage management system
First Claim
1. A method for remapping data in a storage management system having backup data that enable restoration of historical data of a storage system, the method comprising:
- receiving at least one access request for a first set of historical data;
identifying a second set of historical data, wherein the first set of historical data is a subset of the second set of historical data;
identifying, in the storage management system, one or more storage locations containing backup data for the second set of historical data; and
storing a mapping list of the one or more identified storage locations to facilitate subsequent access requests for any of the second set of historical data.

8. A method for remapping data in a storage management system having a time store and a current store, the current store maintaining a mirror copy of current data of a storage system and the time store recording copy-on-write data for historical data of the storage system, the method comprising:
-
selecting a zone in the storage system for which access requests for historical data are anticipated;
identifying, in the time store, one or more first storage locations containing copy-on-write data for the historical data associated with the zone; and
recording the one or more first storage locations in a mapping list to facilitate subsequent access requests for the historical data associated with the zone. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
