If you don't care about possible data relationships in the library syncing with other libraries you will be fine using *LIB. *LIB synchronizes the entire library. *SYSDFN only synchronizes each object to itself: aka data could be out of sync.

Subject: Save While Active
I'm a neophyte when it comes to save while active. I want to save a
smallish production library (under 100GB) during production to replicate it for testing on another machine. I want to do this daily during offpeak (but still production) hours. I noticed a couple of options on the SAVACT: *LIB vs *SYSDFN. Since I'm only saving one lib, *SYNCLIB seems superfluous.
Anyway, does anyone have any recommendations for using save while active? I realize this is what it's meant for, but that doesn't mean there aren't considerations. I'm much more worried about minimizing delays to production than I am about getting a 100% clean image for the test machine. Because of that, I'm leaning towards
SAVACTWAIT(*NOCMTBDY) but I'd love to hear other people's experiences.
