I have Steve Pitcher to thank for sharing this image so that I could post it here. It is from IBM's KnowledgeCenter showing the different types of saves that can be performed using the various save commands, on the right side, and the options on the SAVE menu, on the left.

You can visit the KnowledgeCenter page here.

If you are unfamiliar with the SAVE menu at any command line type:

GO SAVE

And press Enter. The save options mentioned are on the second page of the menu, see below.

I have printed this and stuck it on the wall of my office. Next time we have a discussion about saving types of data from the IBM i we can refer to this to find the appropriate way to get what we want.
