NAME
volcopy - make an image copy of file system
SYNOPSIS
volcopy [ -F FSType ] [ -V ] [ generic_options ]
[ -o FSType-specific_options ] operands
AVAILABILITY
SUNWcsr
DESCRIPTION
volcopy makes a literal copy of the file system.
operands generally include the device and volume names and
are file system specific. A detailed description of the
operands can be found on the FSType-specific man pages of
volcopy.
The program requests length and density information if this
is not given on the command line or if it is not recorded on
a label on the input media. If the file system is too large
to fit on one reel, volcopy prompts for additional reels.
Labels of all reels are checked. Tapes may be mounted
alternatively on two or more drives. If volcopy is inter-
rupted, it asks if the user wants to quit or wants to escape
to a shell. In the latter case, the user can perform other
operations (for example, labelit(1M)) and return to volcopy
by exiting the shell.
OPTIONS
-F Specify the FSType on which to operate. The
FSType should either be specified here or be
determinable from /etc/vfstab by matching the
operands with an entry in the table. Other-
wise, the default file system type specified
in /etc/default/fs will be used.
-V Echo the complete command line, but do not
execute the command. The command line is
generated by using the options and arguments
provided by the user and adding to them
information derived from /etc/vfstab. This
option should be used to verify and validate
the command line.
generic_options
Options that are commonly supported by most
FSType-specific command modules. The follow-
ing options are available:
-a Require the operator to respond
"yes" or "no" instead of simply
waiting ten seconds before the copy
is made.
-s (default) invoke the DEL if wrong
verification sequence.
Other options are used only with 9-track mag-
netic 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.
-o Specify FSType-specific options in a comma
separated (without spaces) list of suboptions
and keyword-attribute pairs for interpreta-
tion by the FSType-specific module of the
command.
FILES
/etc/vfstab list of default parameters for each file
system
/etc/default/fs default local file system type. Default
values can be set for the following
flags in /etc/default/fs. For example:
LOCAL=ufs.
LOCAL: The default partition for a command
if no FSType is specified.
