DESCRIPTION
The
volcopy
command makes a literal copy of an HFS file system
using a block size matched to the device.
Options
volcopy
recognizes the following options:
- -F hfs
Specifies the HFS file system type.
- -a
Invoke a verification sequence
requiring a positive operator response
instead of the standard delay before the copy is made.
- -s
(default) Invoke the DEL-if-wrong verification sequence.
- -y
Assume a
yes
response to all questions
- -V
Echo the completed command line, but perform no other actions.
The command line is generated by incorporating
the user-specified options and arguments
with other information derived from
/etc/fstab.
This option allows the user to verify the command line.
Other options are used with 9-track magnetic tapes:
- -bpi density
Bits per inch.
- -feet size
Size of reel in feet.
- -reel num
Beginning reel number for a restarted copy.
- -buf
Use double buffered I/O.
The
volcopy
command requests length and density information
if they are not given on the command line
and they are not recorded on an input tape label.
If the file system is too large to fit on one reel, the
volcopy
command prompts for additional reels.
Labels of all reels are checked.
Tapes can be mounted alternately on two or more drives.
If the
volcopy
command is interrupted,
it asks if the user wants to quit
or wants to escape to the command interpreter.
In the latter case, other operations (such as executing the
labelit
command) can be performed before returning to the
volcopy
command by exiting the command interpreter.
- fsname
The file system name on the device (e.g.,
root)
being copied.
- special
The physical disk section or tape (e.g.,
/dev/rdisk/disk1
or
/dev/rtape/tape4QIC150).
- volname
The physical volume name;
it should match the external sticker.
Such label names are limited to six or fewer characters.
The argument
volname
can be
-
to use the existing volume name.
- special1
The device from which the copy of the file system is being extracted.
- volname1
The volume from which the copy of the file system is being extracted.
- special2
The target device.
- volname2
The target volume.
The
labelit
command can be used to provide initial labels
for unmounted disk or tape file systems.
With the optional arguments omitted, the
labelit
command prints current label values.
The
-n
option provides for initial labeling of new tapes only
(this destroys previous contents).
The
-F
and
-V
options can be specified for the
labelit
command.
The behavior of the
-F
and
-V
options is similar to their behavior in the
volcopy
command.
