Re: The problem with SAVCHGOBJ . . .

Rob,

We used to do a SAVLIB/SAV once a week here, with a SAVCHGOBJ everyday.
Also, a library with our Backup & Recovery CLs and procedures, SAVSECDTA,
SAVCFG and a file with a list of libraries was saved daily.

Besides the small detail of what would happen when you create a lib on a
Monday and lose it on Friday (just before Saturday's SAVLIB), if your
SAVCHGOBJ uses REFDATE(*SAVLIB), you only have to restore the latest
SAVCHGOBJ tape (not need to "Restore from every daily SAVCHGOBJ").

Our recovery sequence (never needed it, fortunately), was something like
RSTOBJ from the last SAVCHGOBJ and then a RSTOBJ from the last SAVLIB with
OPTION(*NEW), MBROPT(*NEW) (A previous process would have made sure of
creating any missing library)

What is one's restore plan with SAVCHGOBJ?

Scenario 1: Hosed up file A in library B.
Check out the last save date. Use media from that time period.

Scenario 2: Have to restore an entire library.
Restore from GO SAVE 21. Restore from every daily SAVCHGOBJ starting with
oldest to newest?

We briefly looked at SAVCHGOBJ. We decided that
A - It complicated a restore.
B - So many things are changed daily that it really didn't save us much
time. For example, let's say the biggest items in your file library are
the item master, item history, sales history, customer order and customer
order line file. Can anyone imagine a "going concern" not having those
changed on a daily basis?

However, I ran a little sql. Apparently 85% (by size) of our objects are
not changed daily. And that's just in our file library for BPCS.
