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 quota for a volume is 2 terabytes (2^41 bytes).
Note that this only affects the volume's quota; a volume may grow much
larger if the volume quota is disabled. However, volumes over 2
terabytes in size may be impractical to move, and may have their size
incorrectly reported by some tools, such as fs_listquota(1).
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
/usr/afs/etc/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 /usr/afs/etc/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".
