RE: Backup before release update

And while you can probably restore from your other methods, when you're in 
your 19th hour of downtime and getting a little groggy, it helps to be 
able to follow the IBM manuals for a simple restore.

RE: Backup before release update






Jeff,

I'd probably substitute the Option 21 save for your Friday night 
procedure,
then you'll be all set to proceed with your upgrade on Saturday. If you 
rely
on the Friday morning backup, and the Friday night procedure, you leave 
all
of the work done on Friday exposed to loss. You are also excluding some
items in your IFS file system from your Friday night backup. 

One of the reasons for performing the option 21 save is that although the
likelihood a serious problem during the OS upgrade is low, if you do
encounter a problem, it can get very bad, very quickly, and you will want 
a
way to recover to your pre-problem configuration.

Subject: Backup before release update

I am planning on installing V5R3 (from V5R2) this weekend.  In the past I
have always done a GO SAVE option 21 just prior to upgrading releases.  In
thinking about this, I have a question in regards as do I really have to 
do
this.

Every Friday night we do the following backup:

                 SAVSECDTA
                 SAVCFG (along with RTVCFGSRC and saving that object as 
well)
                 SAVLIB *NONSYS
                 SAVDLO DLO(*ALL)
                 SAV OBJ(('/*') ('/QSYS.LIB' *OMIT) ('/QDLS' *OMIT) +
             ('/ImageCatalogs' *OMIT)) 

Friday morning I will do the following backup:

                 SAVSYS
                 SAVLIB LIB(*IBM)

If I do both the above, does the option 21 save really gain me anything? 
If
a recovery is necessary to where I have to reload everything, I know I can
reload from the option 21 save.  Can I reload from the SAVSYS?

The upgrade guide says on page 55 "Tapes that are created with the Save
System (SAVSYS) command cannot be used with the automatic install process.
These tapes also do not provide a complete backup."  I understand the 
second
sentence.  Is the first sentence telling me I can't _reload_ from the 
SAVSYS
or that I just can't do an automatic install?

Do the rest of you do an option 21 save just before any release upgrade, 
or
use your regular backup strategy as being sufficient?

Thanks.
