RE: Full save with IASP

Justin:

That's one of the big reasons iASP was created was to do just what you are
doing now.

While Rob is correct that the save/restore times for IFS based objects is
depended on a bunch of factors, it really does not matter much if it's in an
iASP or not.

The trick is determining if the iASP is volatile to the point where it needs
frequent back up, or is it reasonably static? You can do a full save of the
*SYSBAS objects without the iASP to set that up for recovery, clearly saving
time there, and then save the iASP on a separate save. I do this since a
recovery is two steps anyway. Also depending on the reason for the recovery
on *SYSBAS you may not need to recover the iASP independently anyway.

So:
1) Buy BRMS and let it back up the system while you sleep. Does it
automatically. Three months of your time and it pays for itself. It will
handle the iASP too. Backup *SYSBAS, start the system then back up iASP.
Simple.

2) Set up two saves. One for the *SYSBAS and do that one at 0:darkthirty as
needed. The second save can be done any time you want to just to the iASP,
again depending on the data you put there.

Oh Lordy...
Save times may vary with IFS based on a number of factors
- Number of IFS objects
- Size of each individual IFS object
- Disk speed
- Speed of backup media.
- Whether you specify ASYNCBRING on your SAV command. Prompt the help on
that.
- How many drives in your library you use

We're looking at replacing our 720 with an S914. In the process, I'd like
to add an independent ASP to store about 1 TB of PC-type files that are
currently stored externally. My question is how this will affect a full
system save. I currently do a GO SAVE 21 the wee hours of the morning,
the first Sunday of the month. I'm concerned that the extra files will
overrun my backup window.

I've never had an independent ASP, so I don't know what my options are. Is
there a good way to handle this?

TIA
