Can I just do a SAVSECDTA & SAVCFG instead of SAVSYS? Will it be sufficient if i need to revert back to the status before load in PTFs?
Personally… I run a SAVSYS after I apply PTF's in order to have a current backup of my system configuration. If for some reason I had to restore the system to a state prior to the most current application of PTF's, I'd recover from my previous SAVSYS tape.
Mary wrote us to amend the answer, her comments follow:
SAVSYS is not enough, SAVLIB *IBM also needs to be done because that is where the PTF's live depending on which IBM OS product the PTF is for.
