RE: Multiple backups on single tape?

Brian,

I don't think that this a choice, at least for the SAVSYS and SAVSTG
commands.  Look at the CLEAR parameter on both commands.  Your choices
are to clear all the data on the tapes or abort the procedures.  This
makes it clear to me, at least for these two commands, that putting at
the end of active files is not an option.

In a way, this makes sense.  The main purpose of either of these saves
is to recover a system, often at power up without operator intervention
which would allow the specification of a file sequence number.  When
powering back up from a crash, you have a tape with three SAVSYS's on it
and need to reload your system.  What do you do?  How could you tell the
system to use the middle one?

Andy Nolen-Parkhouse
