Re: Back ups with High Availability Web Server

OK so you can't 'exactly' but you can save the delta between your most 
recent SavSys and today.

First you take a SAVSYS at some point. Perhaps you've already done that 
so don't overwrite it, this becomes the starting point.

Next when you do PTFs on the partition use the 'COPY PTF's option in GO 
PTF option 8. (Select 'Other options' to see this.)  Or if you use the 
INSPTF command instead add CPYPTF(*YES).  Now if you're prefer not to 
have to remember to specify this, enter CHGSRVA CPYPTF(*YES) to change 
the default for both of the above options.

Now when you do PTFs *SAVFs will be created in QGPL for each ptf that is 
applied. You will need to leave these there and not clean them out until 
your next actual SavSys.

To 'Save While Active' your system use the SAVSYSINF command. This will 
save a subset of what SAVSYS does but does not need a dedicated system.

To restore you would install the system from the SAVSYS media and then 
add the most recent SAVSYSINF with RSTSYSINF. This will bring the system 
up to current with respect to this part of the save.

When you are talking about totally different operating systems you are going to have to expect there are some differences in operation.  You will have to learn how to open your mind and try to understand.  One of Stephen Covey's books was "7 habits of Highly Effective People".  In there, one of the habits was "seek first to understand".  Read the book.  If a semi driver was to jump into my car and the first thing he noticed was there was no clutch it doesn't necessarily make my car worthless.

There is one command that is supposed to save your entire system and not allow a granular restore.  That is SAVSTG.  If you aren't currently using it do NOT bother trying to study it.  You do not want to use it.  And I will leave it at that for now.
