  1.           BACOPY (Backup Directory)                  John Dickinson
  2.           Command                                          No. 2
  3.           _______________________________________________________
  4.  
  5.           Purpose:  Backs up all (or selected) files in a
  6.                     directory to hard or floppy disks, permitting
  7.                     disk changes when target disks become full.
  8.  
  9.           Format:   BACOPY [d:][path]filename[.ext] [d:][path]
  10.  
  11.           Remarks:  Unlike the DOS COPY command, BACOPY.COM permits
  12.                     you to change (formatted) target disks when
  13.                     backing up files to disk.  Furthermore, it
  14.                     only backs up files whose date stamp is later
  15.                     than those of identically named files on the
  16.                     target disk.  Unlike BACKUP, BACOPY does not
  17.                     change the setting of the archive bit.  Also,
  18.                     files copied with BACOPY.COM are fully usable at
  19.                     all times; they do not need first to go
  20.                     through a RESTORE process.
  21.  
  22.                     BACOPY.COM supports the use of global (* and ?)
  23.                     characters in filenames and extensions.  It
  24.                     does not, however, permit you to REName files
  25.                     during copying.
  26.  
  27.           Example:  You are working at a PC AT with a hard disk
  28.                     drive (C:) on which you keep your copy of
  29.                     BACOPY.COM, and you want to back up all the .DOC
  30.                     files stored on a 1.2-Mb floppy disk (drive
  31.                     A:) onto  regular 360K disks (drive B:).
  32.                     Since these .DOC files will require
  33.                     approximately 600K, you must have two
  34.                     formatted blank floppy disks ready to use in
  35.                     drive B:.  From the C> prompt you enter
  36.  
  37.                          BACOPY A: *.DOC B:
  38.  
  39.                     When the first target disk in drive B: is
  40.                     full, you will be prompted to change disks.
  41.  
  42.                     Notes:
  43.  
  44.                     1.   BACOPY.COM compares the date stamps of
  45.                          identically named files and will not
  46.                          overwrite a newer version with an older
  47.                          one.  This may cause files to be skipped
  48.                          if you omit to keep your date/time
  49.                          current.
  50.  
  51.                     2.   Requires DOS 2.0 or later.
