Stabackit does only ONE "SET FILE/ENTER" worth noting; to wit:   it  uses  the
command:

$ SET FILE/ENTER=SYS$SYSDEVICE:[SYSE]SYSCOMMON.DIR SYSDEVICE:[000000]SYS0.DIR

Now, this DOES mean that any file that  you  delete  from  [SYSE.SYSCOMMON...]
will  likewise  disappear  from  [SYS0....],  but  it has the rather desirable
effect of  obviating  the  necessity  of  copying  all  your  device  drivers,
shareable images, and so forth, from your system directories to the standalone
backup directory.  Stabackit copies only a  handful  of  files  into  its  own
private directory, and these are things like the system parameter files, where
standalone backup and your system want to use different parameter values.   If
you  want  to  get rid of thestandalone backup kit, you need only set one file
/remove, then delete about half a dozen  files  from  the  private  directory.
This  as compared to having a second copy of half your operating system kernal
sitting around on disk.  Given this, any  private  copy  of  stabackit.com  is
likely  to run slower than the one that DEC supplies, to result in more wasted
disk space, and be liable to things like your forgetting to update  the  files
in  your  standalone  backup  directory  when  you  make changes (patches, for
example) to files in your system directories.
