 Name

    volcopy - make literal copy of UNIX filesystem

 Syntax

    /etc/volcopy [ options ] fsname srcdevice volname1
    destdevice volname2

 Description

    The volcopy command makes a literal copy of the UNIX filesystem using a
    blocksize matched to the device.  The options are:

    -a   invoke a verification sequence requiring a positive operator
         response instead of the standard 10-second delay before the copy is
         made.

    -s   (default) invoke the ``DEL if wrong'' verification sequence.

    The program requests length and density information if it is not given on
    the command line or is not recorded on an input tape label.  If the file-
    system is too large to fit on one reel, volcopy will prompt for addi-
    tional reels.  Labels of all reels are checked.  Tapes may  be mounted
    alternately on two or more drives.  If volcopy is interrupted, it will
    ask if the user wants to quit or wants a shell.  In the latter case, the
    user can perform other operations (for example, labelit) and return to
    volcopy by exiting the new shell.

    The fsname argument represents the mounted name (for example, root, u1,
    etc.)  of the filesystem being copied.

    The srcdevice or destdevice should be the physical disk section or tape
    (for example:  /dev/dsk/0s1 etc.).

    The volname is the physical volume name (for example:  pk3, t0122, etc.)
    and should match the external label sticker.  Such label names are lim-
    ited to 6 or fewer characters.  volname may be ``-'' (dash) to use the
    existing volume name.

    srcdevice and volname1 are the device and volume from which the copy of
    the filesystem is being extracted.  destdevice and volname2 are the tar-
    get device and volume.

    fsname and volname are recorded in the last 12 characters of the super
    block (char fsname[6], volname[6];).
