The rudimentaries for this already exist via the DMAPI interface in GPFS 
(used by the TSM HSM product). A while ago this was posted to the IBM

This log can be used to generate backup sets etc.  Unfortunately, a bug in the current DMAPI keeps this approach from working in the case of certain events.  I am told 3.4.0.3 may contain a fix.  We will gladly share the code once it is working.
