John, I do something close to this with exports. I run exports to a special sms defined pool of volumes; HSM migrates this pool every hour. I can run any number of exports to devt=file without running out of space. Imports work fine once I recall the files.
I rename each file so that a del volhist doesn't delete the files; the files don't need to have their original tsm assigned names to be imported and I expect the same is true for backupsets. This method implements what so many people have asked for lately, which is multiple exports or backupsets to one tape. Hope this helps, -- -------------------------- Bill Colwell C. S.
