Abstract
Various embodiments are directed to systems and methods for creating an archive of a set of logical storage units stored on at least one storage medium. A first plurality of LSU descriptors may be generated. Each LSU descriptor may describe a current version of one of the set of LSUs at about the time of the generating. A first archive may be read to produce a first archive plurality of LSU descriptors. Each of the first archive plurality of LSU descriptors may describe a version of one of the set of LSUs when the first archive was created. The first archive plurality of LSU descriptors may be compared with the first plurality of LSU descriptors to identify a first LSU from the set of LSUs that has an associated LSU descriptor that does not match a corresponding LSU descriptor from the first archive plurality of LSU descriptors.
