DESCRIPTION

       The vos copy command makes a copy of a volume with a new name.  It is equivalent to vos dump followed by vos restore, but doesn't require
       the volume be stored locally by the client.

CAUTIONS

       Currently, the maximum size of a volume is 2 terabytes (2^31 bytes).

OPTIONS

       [-id] <volume name or ID>
	   Specifies either the complete name or volume ID number of a read/write volume.

       [-fromserver] <machine name for source>
	   Identifies the file server machine where the source volume resides. Provide the machine's IP address or its host name (either fully
	   qualified or using an unambiguous abbreviation). For details, see vos(1).

       [-frompartition] <partition name for source>
	   Names the partition where the source volume resides. Provide the full partition name (for, example, /vicepa) or one of the abbreviated
	   forms described in vos(1).

       [-toname] <volume name for new copy>
	   The complete name of the new volume to create.

       [-toserver] <machine name for destination>
	   Identifies the file server machine to which to copy the volume.  Provide the machine's IP address or its host name (either fully
	   qualified or using an unambiguous abbreviation). For details, see vos(1).

       [-topartition] <partition name for destination>
	   Names the partition to which to copy the volume. Provide the full partition name (for, example, /vicepa) or one of the abbreviated
	   forms described in vos(1).

       -offline
	   Leaves the new volume flagged as off-line in the volume database.

       -readonly
	   Flags the new volume as read-only in the volume database.

       -live
	   Copies the live volume without cloning.  This is normally not necessary and causes the volume to be kept locked for longer than the
	   normal copy mechanism.

       -cell <cell name>
	   Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see vos(1).

       -noauth
	   Assigns the unprivileged identity "anonymous" to the issuer. Do not combine this flag with the -localauth flag. For more details, see
	   vos(1).

       -localauth
	   Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The vos command interpreter presents it to the
	   Volume Server and Volume Location Server during mutual authentication. Do not combine this flag with the -cell argument or -noauth
	   flag. For more details, see vos(1).

       -verbose
	   Produces on the standard output stream a detailed trace of the command's execution. If this argument is omitted, only warnings and
	   error messages appear.

       -encrypt
	   Encrypts the command so that the operation's results are not transmitted across the network in clear text. This option is available in
	   OpenAFS versions 1.4.11 or later and 1.5.60 or later.

       -noresolve
	   Shows all servers as IP addresses instead of the DNS name. This is very useful when the server address is registered as 127.0.0.1 or
	   when dealing with multi-homed servers. This option is available in OpenAFS versions 1.4.8 or later and 1.5.35 or later.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT

       This command has no output unless "-verbose" is specified or there is an error.

EXAMPLES

       The following example makes a verbose copy of the "test" volume named "test2" in the cell "localcell". The volume and copy both reside on
       "/vicepa" of "server1".

PRIVILEGE REQUIRED

       The issuer must be listed in the /etc/openafs/server/UserList file on the machine specified with the -server argument and on each database
       server machine. If the -localauth flag is included, the issuer must instead be logged on to a server machine as the local superuser "root".
