VOLCOPY(ADM)                         UNIX System V



     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.  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 filesystem is too large to  fit  on  one
          reel,  volcopy  will prompt for additional 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 (e.g., labelit)
          and return to volcopy by exiting the new shell.

          The fsname argument represents the mounted name (e.g., root,
          u1, etc.)  of the filsystem being copied.

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

          The volname is the physical volume name (e.g.:  pk3,  t0122,
          etc.)   and  should  match the external label sticker.  Such
          label names are limited to six or fewer characters.  volname
          may be - 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 target device and volume.

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