I backup everything.
Why?
In a real disaster, you don't have a system's programmer.
Since you already have to document and teach how to do a standalone restore of
the system packs, just repeat for the page/spool/tdisk packs.
Formatting and allocating packs is another source of errors. And when
Hi Anne,
Our DR restores are done under a VM system that is available at the DR
site. We include a spool offload tape (actually 2 of them, one for
spare) with the NSS backups on it and a few PUN files on the same
tape. One of those PUN files is the DSF commands necessary to format
page and spool,
We backup cyl 0 (zero) of the page packs just to avoid having to run
ICKDSF to put a label on the packs. We then, of course, restore that
cyl 0 at DR.

Don't you still need to format 1-END? In my experience, you can end up
with paging errors if the dasd isn't initialized/formatted. Haven't tried
just cylinder 0 though, so I could be wrong..

You will need spool space, so you might as well copy it (or keep a small spool
area available only with the NSS files, JUST for DR).
Time to resubmit that requirement for disk support for SPXTAPE.

David, CP doesn't need a PAGE pack to start: it can and will page in spool

This method works fine, however, I’m wondering if backing up the page packs
is necessary?

Normally, I suppose you would. But the packs are preformatted for us.
