The only time I used SAVSTG seriously was when I managed a LAB box.

after upgrades, ptf's etc, i would run a savstg.
If you needed the lab box, i would give you QSECOFR and turn it over to you.

When I got it back, I scratched everything back to the SAVSTG.
So, I have never tried RSTSTG to another box.

I gather a SAVSTG is more like a DISK IMAGE. -- bit processing.
I think this is where the hardware differences come in.
I think the new disks need to be the same number and at least the same 
capacity as the saved machine.

So, I think it may be quicker to run,
definitely easier to scratch a box "back to" that image.
but, imho, not a serious contender for daily / weekly saves.
I would rather see a Opt 21 with Save-Changes in between until you can do 
another full backup
before I would recommend a SAVSTG.
