Hello Jim,

thanks for that highly interesting insight!

The answer to your last question is yes, there will be objects not in tape that were on the partition during the save.

Yuck!

That said, IBM marks objects to not back up it knows the system can recreate.

That generates more questions. :-)

A better way to look at it is an object can be built be the OS and used by the OS is an IBM object, I refer to them as “IBM objects”. Any object that might contain “user data” meaning not created and maintained by the OS is a “User Object” (meaning not IBMs) something that needs to be saved. This holds true regardless of its storage location and it it is structured or unstructured data.

Understood.

So, if a directory (tree) with IBM objects is missing (due to e. g. a Restore 21 happening prior), those are recreated? When? At IPL time? At the right time — when they are requested by whatever?

IBM does create objects that get user data in them (ie: http configuration files) and those are “user data” objects.

Are these also excluded from saves with attributes? If no — all fine. If yes — drat!

:wq! PoC
