The current method might be called GO SAVE 21 UNATTENDED or no operator
involved once it starts good.

The old method was GO SAVE 21 with OPERATOR guiding it from start to finish
... the reason for the old method was mainly our inexperience with the system.

Step 1 was pretty much the same deal.

until we got good with WRKACTJOB variants
we were doing lots of phone calls to remote sites

We now use naming convention of IBM01 for Monday nite backup
IBM02 IBM03 IBM04 IBM05 Tues Wed Thu Fri

Because I managed to persuade management that it was more economical to buy
IBM brand that goes several years before it flakes out, as opposed to el
cheapo which dies when you least expect it & then you have to run that backup
again & how do you know that last nite's backup is any good ...IBM log might
say everything went fine, but the media is about to die.

When we were using different brands of tapes from different vendors that sold
tapes & they died before the warranty ran out, we had to know which vendor
sold us this when, so I had a tape naming convention that included 2-3
letters for each of:
Brand name of media
Vendor that sold it to us
What density is this thing ... 2 Gig or whatever
When it arrived in our system
When we first used it
digit or character on end ... tape A B C D etc. where all the above stuff the

I had an INZTAP prompt screen CL in which I would fill in name of vendor etc.
to get the naming convention taken care of

Every time after some tapes died, I needed to review both naming conventions
... what shall we call the next tapes, and problem history, so I could fight
the battle to get EL QUALITY instead of EL CHEAP

STRSST /1 /1 /4 activity log on removable media

To initialize tapes if you have not setup what you always do on some menu
like I have

or GO TAPE /2

We did not know that originally ... we thought the OJ light meant time to
clean it once.  This probably contributed to more rapid demise of our tape
media & drives.

We did not know that either ...
which probably contributed to some of the problems we had

We learned the hard way with GO BACKUP that even though the 400 could backup
the important stuff concurrent with printer running (big help when end-month
got a few thousand pages to print) it was not worth the headaches digging
into error messages after backup to make sure the only reason we had the
error messages was the printer was running.

I think it is WRKUSRJOB *ALL *ALL that gets you all non-system jobs on your
system, including running right now, waiting in JOBQ etc & by futsing around
with F4 you can exclude from consideration those that have gone to a

I may do a later post pointing at some of the gotchas that we found out
about, and cared enough to document.

>  5. GO SAVE 21

Since we were also doing GO BACKUP a lot, our instructions reminded people
which menu they should be on.

Also gotta be on the main console signed on as Master Security Officer.

We were klutzes so we put ourselves into *BREAK message mode just to be on
the safe side, even though a later step does that for us.

When there are already a lot of unanswered messages on QSYSOPR that are
unrelated to the backup, let's review them before starting the backup.

Take your time filling in the screen & roll back & forth to make sure answers

You really really do not want to be doing it the way we used to do it ... it
would stop every 10-15 minutes with another screen for us to fill out & we
had copious notes how to fill out each screen

Quite recently we had this scenario:
The boss told me he was done with end-fiscal stuff & I could do the nitely
I started the backup.
He came in saying there was one more report he wanted to do & could I
interrupt it.
I told him, yes I can & I want you to see how, because I have never shown you
how to interrupt a dedicated restricted state task (my boss does backups when
I am on vacation), but I warn you in advance that the time lost will be
How significant he wanted to know
I guess about an hour or so
Ok show me.
So I showed him
We lost like 2 1/2 hours (the backup normally takes 1 1/2 hours)
I told him that now he knows how to do a really useful thing, but the lesson
is that if you need something in the future, it will be done faster if we
wait on the backup getting finished & if you want to leave, perhaps leave me
instructions how to do it when the backup is done.
This was a month before the tape drive died & when that was fixed I learned
some stuff about cleaning tape drive more aggressively to get better

If anything goes wrong with the backup, such as error messages at the end.

SIGNOFF *LIST so there is a detail job log on the episode.
Then print with SAVE(*YES) first.
