Re: IFS backup to Disk

[Jim Oberholtzer <midrangel@xxxxxxxxxx>]

Another alternative would be to create an image catalog and use Virtual 
Tape.  That way the tape image can just be duped to physical tape 
providing for a single step recover directly from the physical tape, 
instead of having to restore the save file and then restore the needed 
object.

Additionally a virtual tape will allow you to run whatever save 
operations you would like onto one tape whereas the save file will only 
allow one save operation

Uses about the same amount of space on disk.

Virtual tape requires a bit more setup, but provides direct restore 
capability
Save files are really simple to set up, but require a two step restore, 
and only allow one save operation to the save file

Strong caveat:  Performance of a save to disk it heavily dependent on 
the DASD arm utilization and how many arms you really have available.  
On a small system you may find the performance of a save to save file or 
Virtual tape to actually be slower than to a physical tape device.  In 
short your performance of the save will vary based on your configuration.
