       -j     Do not copy junk:  *.Z, *.bak, a.out, core, etc

       backup /bin /usr/bin
			   # Backup bin from RAM disk to hard disk

DESCRIPTION

       Backup (recursively) backs up the contents of a given directory and its subdirectories to another part of the file system.  It has two typ-
       ical uses.  First, some portion of the file system can be backed up onto 1 or more diskettes.  When  a  diskette  fills	up,  the  user	is
       prompted for a new one.	The backups are in the form of mountable file systems.	Second, a directory on RAM disk can be backed up onto hard
       disk.  If the target directory is empty, the entire source directory is copied there, optionally compressed to save space.  If  the  target
       directory  is  an  old  backup,	only  those  files  in	the target directory that are older than similar names in the source directory are
       replaced.  Backup uses times for this purpose, like make.  Calling Backup as Restore is equivalent to using the -r  option;  this  replaces
       newer files in the target directory with older files from the source directory, uncompressing them if necessary.  The target directory con-
       tents are thus returned to some previous state.
