RE: need to move from monthly full save, fix apply, IPL to semi-annually

["Musselman, Paul" <pmusselman@xxxxxxxxxxxxxxxx>]

Gerald--

We use IBM i methods-- we have the luxury of running a full Option/21 every night.  A far cry from when we could only do that once every 3 years before an OS upgrade!!

We actually run a program that includes all of the commands that make up the Option/21; lets us run under program control instead of having an operator standing by.

Paul,
do you back up the clone via IBMi or BRMS methods?
