RE: Creating nightly full backups (Lukas Beeler)

Hi,

If you have BRMS, use BRMS.

We do not have BRMS. But since V5R3, SAVSYS can run in batch mode and ENDSBS 
has the DELAY parameter (STRSBS automatically initiated after this delay time). 
So we can start automatically a GO SAVE 21 like job running in QCTL. We run 
that job once a week.

Our production system is a i520 and we have also a test (820) and a backup 
system (720). I could totally load the i520 system on 820 and on 720 without 
any problem by using the backup tape issued from this GO SAVE 21 job. You have 
only to adapt the configuration.

We also use IBM's UNIX system, AIX, on several servers. We could experience 
that reloading a system from one platform to another works well, even if the 2 
servers are different models.

I know it works on our big MVS systems too. So IBM made good job in restoring 
systems.

What about Windows ? I agree that restoring Windows systems on servers is not 
so easy... Try and we speak about.

You programmers are right.  You can only get the *SAVSYS when the 
system is in restricted mode.  Not really that big of a deal because 
that only changes when you put PTFs or upgrade OS.  Do a full system 
save and send that off site, at the same time make a *SAVSYS tape that 
you can leave 'at the office' if it's that important.

Do yourself a favor and start using BRMS.  Every night make sure the 
last thing you do is backup the object information in the BRMS 
databases.  When you run the maintenance job everyday (expires tapes, 
moves them from location to location, etc), you get an awesome report 
that tells you step by step how to restore the system.

As a side note, ask the Windows guys if they've ever tried to restore 
that *full system save* on another system?  I bet they haven't.  
Windows doesn't like being restored to different hardware.  Our 
Distributed Conmputing team moved to running alot the Windows servers 
on VMWare just for that reason since VMWare vitualizes the hardware. 
Hmm, where have I seem a system that does that for you?  When we went 
to our IBM disaster recovery test, I would restore the Mainframe (in a 
VM partition) and iSeries without any problems and they'd be pounding 
their heads on the wall.

I don't know if you have a disaster recovery contract with anyone or 
need one for that matter, but we have ours with IBM.  In addition to 
the nice report that BRMS, IBM supplies me with a step by step screen 
shot writeup to IPL the system from tape, selecting disk from DST, etc.
