DESCRIPTION

       The vos restore command converts a volume dump file previously created
       with the vos dump command from ASCII into the volume format appropriate
       for the machine type indicated by the -server argument, and restores it
       as a read/write volume to the partition named by the -partition
       argument on that machine. The Volume Server assigns the volume name
       indicated with the -name argument, and resets the volume's creation
       timestamp to the time at which the restore operation begins (the
       creation timestamp is stored in the volume header and reported in the
       "Creation" field in the output from the vos examine and vos listvol
       commands.)

       Use the -file argument to name the dump file, or omit the argument to
       provide the file via the standard input stream, presumably through a
       pipe. The pipe can be named, which enables interoperation with third-
       party backup utilities.

       As described in the following list, the command can create a completely
       new volume or overwrite an existing volume. In all cases, the full dump
       of the volume must be restored before any incremental dumps. If there
       are multiple incremental dump files, they must be restored in the order
       they were created.

       ·   To create a new read/write volume, use the -name argument to
           specify a volume name that does not already exist in the Volume
           Location Database (VLDB), and the -server and -partition arguments
           to specify the new volume's site. It is best to omit the -id
           argument so that the Volume Location (VL) Server allocates a volume
           ID automatically. Do not include the -overwrite argument, because
           there is no existing volume to overwrite.

       ·   To overwrite an existing volume at its current site, specify its
           name and site with the -name, -server, and -partition arguments.
           The volume retains its current volume ID number unless the -id
           argument is provided. Specify the value "f" or "i" for the
           -overwrite argument to indicate whether the dump file is full or
           incremental, respectively.

       ·   To overwrite an existing volume and move it to a new site, specify
           its name and the new site with the -name, -server, and -partition
           arguments. The volume retains its current volume ID number unless
           the -id argument is provided. The volume is removed from its
           original site. Specify the value "f" for the -overwrite argument to
           indicate that the dump file is a full dump (it is not possible to
           restore an incremental dump and move the volume at the same time).

       If the volume named by the -name argument already exists and the
       -overwrite argument is omitted, the command interpreter produces the
       following prompt:

          Do you want to do a full/incremental restore or abort? [fia](a):

       Respond by entering one of the following values:

       ·   "f" if restoring a full dump file

       ·   "i" if restoring an incremental dump file

       ·   "a" or Return to cancel the restore operation

CAUTIONS

       If the -file argument is omitted, the issuer must provide all other
       necessary arguments, because the standard input stream is unavailable
       for responding to the command interpreter's prompts for missing
       information. In particular, the issuer must provide the -overwrite
       argument if overwriting an existing volume.

OPTIONS

       -server <server name>
           Identifies the file server machine onto which to restore 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).

       -partition <partition name>
           Identifies the partition (on the file server machine specified by
           the -server argument) onto which to restore the volume. Provide the
           partition's complete name with preceding slash (for example,
           /vicepa) or use one of the three acceptable abbreviated forms. For
           details, see vos(1).

       -name <name of volume>
           Specifies the name under which to restore the volume. It can be up
           to 22 characters long, but cannot end with a ".readonly" or
           ".backup" extension. If the volume already exists, it is
           overwritten subject to the value of the -overwrite argument.

       -file <dump file>
           Names the dump file to restore. Incomplete pathnames are
           interpreted relative to the current working directory. Omit this
           argument to provide the dump file via the standard input stream.

       -id <volume ID>
           Specifies the volume ID number to assign to the restored volume.

       -overwrite (a | f | i)
           Specifies which type of dump file is being restored when
           overwriting an existing volume. Provide one of the following
           values:

           ·   "a" to terminate the restore operation.

           ·   "f" if restoring a full dump file.

           ·   "i" if restoring an incremental dump file. This value is not
               acceptable if the -server and -partition arguments do not
               indicate the volume's current site.

           This argument is mandatory if the -file argument is not provided.

       -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.

       -creation <dump | keep | new>
           Set the creation date of the new volume to the timestamp from the
           dumped volume (dump), from the target volume, if there is one
           (keep), or generate a new one using the current time (new).

       -lastupdate <dump | keep | new>
           Set the last updated date of the new volume to the timestamp from
           the dumped volume (dump), from the target volume, if there is one
           (keep), or generate a new one using the current time (new).

       -nodelete
           This option is available in OpenAFS clients 1.4.7 or later and
           1.5.31 or later. This option can be used with OpenAFS server
           versions 1.4.1 or later and 1.5.0 or later.

       -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.

EXAMPLES

       The following command restores the contents of the dump file
       /afs/abc.com/common/dumps/terry.dump to the /vicepc partition on the
       file server machine "fs3.abc.com". The restored volume is named
       "user.terry".

          % cd /afs/abc.com/common/dumps
          % vos restore -file terry.dump -server fs3.abc.com -partition c \
              -name user.terry

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".
