Again, exploit ADSM facilities to provide as much safeguard comfort as you
desire: use BAckup STGpool, which you can output to multiple copypools in
succession if your needs so require.  Depending upon full backups does not
provide more comfort if that engineer just as readily destroys your full
backup tape.  And don't forget that there are kits and techniques which allow
you to physically recover tape from a damaged cartridge shell or broken leader
as an expedient.
