Re: Tape category *SHARE400 *NOSHARE and restore from type 21 Save

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

Paul:

Two answers:  If you TEST THE RESTORE no I think you'll be OK, but, big
but, until you've tried a recovery, chances are the first one or two will
fail in some way.  Restoring individual objects is a different animal than
a recovery.  So assuming a test and you've stepped on any land mines
already, should be good to go.  It sounds like you understand how to use
the categories well.

Answer 2:  Unless you know the special steps needed for a full recovery,
and have them documented , then you're bound for heartache and headaches if
you really get into a recovery situation.  You'll need help.
