1. A method for generating backup files in a computer system comprising:
generating a full backup file corresponding to a first time for a set of objects in the computer system;
generating at least one incremental file for said set of objects after said first time, wherein each of said at least one incremental file is associated with the set of objects;
identifying a target object within said set of objects for the generation of cumulative backup files; and
generating at least one cumulative backup file corresponding to a second time, after said first time, for said target object, wherein said generating of said at least one cumulative backup file is performed off-line and from calculations with only said generated full back up file and said generated at least one incremental file and not comparison with the set of objects, wherein said at least one cumulative backup file corresponding to a second time allows for the restoration of the target object without the restoration of the set of objects.
