What kind of confusion still exists since the detailed postings of your "understanding, backup creates a copy of OS?"

Maybe Korg Manuals are not most user friendly, but most important procedures are described. Most of that describtions - like how to backup or to save all musical resources - again in essence, they have been repeated here in recent posts of this thread.
But at least something of your own initiative is expected - so please at least read the concerned postings and manuals of your arrangers. As also mentioned there even more is inside as you think.
At the very least, after that, the repeated question should be avoidable, how to do an OS rollback with a backup file (--> Manual p976-979).

It is ok to expect help asking questions here, but you also have to be prepared to accept this help, otherwise it seems a pity to post here.
Why not further detailed question are asked here if still exists confusion? Maybe you get better answers as ever you will get with webinars!
