You can backup to disk by doing a save to a save file (specify *SAVF as the device on your save command).
You’ll need to create the save file first by using the CRTSAVF command.
If you are using BRMS to backup your servers, there is an option on the policy to save to savf instead of tape.
From C007 :-
I think the best thing you can do is to backup these to Ultrium Tape.
First, Creat library and save file
Then Save library
Then Save this library to tape drive
To C007, please don’t wipe other people’s answers out. They’re just as valid as yours.
