Thanks all for the responses. As I suspected it seems nothing has changed as it 
relates to Access databases, so now all I need to deal with is folks that just 
don't understand why "everything" isn't "always" backed up.

As List participants have tried to point out in the past, backing up
the physical files constituting a database while the database
facility is running is shooting in the dark.  Even if you can get a
good backup of the files, that by no means assures that you have
consistent data, given that so many pieces of the database may be in
memory.  Database systems provide access APIs and IBM provides TDPs
based upon them because that's the right way to perform backups on
these dynamic systems.
