Reply with quote

Hi,

I have a case to use ADRDSSU backup about 300 files in 1 step.

include(A.B.C.**)
exclude(A.B.C.D.**
A.B.C.E.**
A.B.C.F.** )

there are 500 files totally with A.B.C.**, and there are 200 files in
the exclude lists.

I just want to know if I list donw all 300 files in include statement,
the performance is better or not?

Anyone have such experience? How ADRDSSU work to backup file.

Hello,

Only marginally.

The time is mostly spent actually copying the data from one place to another, not getting ready to do the copy.

The logical dump / copy uses the catalog structure, and will be much faster than you sitting there coding up 300 include statements, which incidentally would not work instream, so they would have to be put into a filter dataset.

This is the easiest and accepted method, the IBM catalog search facility is a very quick piece of software so any, if there are, savings would almost be immeasurable.
