We have always known that backups using mksysb could be done on a live system - except it may be necessary to stop certain applications that keep meta information in rootvg. That time has been - massively - shortened. And, fortunately, this is "so old" we should all have it by now.

Basically, before generating a list of files to makeup AIX is making a "LVM snapshop" of the rootvg - and then backing up that list of files. So, to be safe - still stop your vital applications BUT! once you see this:

 

Creating snapshots.....
Creating list of files to back up.

You may restart your applications.

FYI: my current backup has the following  extra mounts to support a mksysb to my nim server:
