The question is what do you hope to restore from it.  You will find that a
full backup like this applies to a specific application, not the entire
company.  It is usually a small segment of the corporate data.  In the
mainframe world with tapes for applications you just created a tape with a
specific retention, special backup of that information.  There are probably
a thousand ways to accomplish this in the TSM open world.  The most viable
way in the open systems world is to copy the data files to an archive area
that is archive/deleted and kept for the appropriate period of time.  This
way the application has the responsibility to put the data in the location
at the appropriate time and the storage management solution now manages that
area with a predefined set of criteria that is totally automated.

Yes, this requires a little bit of work for the application.  But, if they
really want data recovery at an application level then this is the most
effective way.  Everyone, knows the archive data areas then and where to
find the archived data.
