Rob,
I understand that you can not do SAVSYS unless all subsystems are inactive. How do I do a SWA with SAVSYS?

Matt,
If you really are serious about trying to understand saving and restoring data on IBM i then I suggest you at least try to read some of the material out there. I would start out with
http://pic.dhe.ibm.com/infocenter/iseries/v7r1m0/topic/rzahg/rzahgbackup.htm
Yes you can do save while active. But you can also NOT use save while active. So, when you say stuff like "Why is it then that GO SAVE, option
21 ends all subsystems?" it sounds sarcastic. I do not think your question is genuine, like you really care why it ends all subsystems. When you are talking about totally different operating systems you are going to have to expect there are some differences in operation. You will have to learn how to open your mind and try to understand. One of Stephen Covey's books was "7 habits of Highly Effective People". In there, one of the habits was "seek first to understand". Read the book. If a semi driver was to jump into my car and the first thing he noticed was there was no clutch it doesn't necessarily make my car worthless.
Another point. Someone like you, coming from a different platform, can challenge us. And open our minds to different possibilities. Cross platform comparisons are good. However, we have to learn to respect each other and not try to belittle each other.
One other thing, the backup link above is not the "end all / be all".
There are other alternatives. There are things like:
- replicating your data to another machine with a high availability solution and doing your backups from there.
- Some other replication solutions, forgive me if I have the wrong term, but perhaps Metro Mirror or some such thing?
- Flash copy. I really do not know much about it at all. I did a little reading about it at:
https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/IBM%20Backup%2C%20Recovery%20and%20Media%20Services%20%28BRMS%29%20for%20i/page/FlashCopy
having to power down the system was a bit of a shocker, or is that how other platforms work with flash copy?
IBM i administrators like to be able to do both full system restores or granular, individual object restores, from the same backup. There is one command that is supposed to save your entire system and not allow a granular restore. That is SAVSTG. If you aren't currently using it do NOT bother trying to study it. You do not want to use it. And I will leave it at that for now.
If you are guesting a partition on another partition of IBM i you can save the entire guest by saving the storage area for that guest on the host.
You cannot do a granular restore from that though.
