[Simh] Simh Digest, Vol 76, Issue 4

[Larry Baker]

Jason,

My recollection is that VMS Backups save sets written directly to tape  
use ANSI labelled tape format.  That made it possible to VMS COPY a  
Backup save set from a mounted tape to disk or from disk to a mounted  
tape.  You would not only have to copy the Backups save set files you  
have on your PC to a SIMH tape file, but you would also have to write  
the proper ANSI tape labels and tape marks.  I think you will find it  
much easier to create a dedicated SIHM VAX disk to hold your Backup  
save sets on a volume that is not your boot volume.  That way you  
don't have to mount the volume with the Backup save sets most of the  
time and they will not use any space on your VAX file system.
