-<P><STRONG>Description</STRONG>
-<P>The <B>vos restore</B> command converts a volume dump file previously
-created with the <B>vos dump</B> command from ASCII into the volume format
-appropriate for the machine type indicated by the <B>-server</B> argument,
-and restores it as a read/write volume to the partition named by the
-<B>-partition</B> argument on that machine. The Volume Server
-assigns the volume name indicated with the <B>-name</B> 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 <TT>Creation</TT> field in the output from the <B>vos
-examine</B> and <B>vos listvol</B> commands.)
-<P>Use the <B>-file</B> 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.
-<P>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.
-<UL>
-<P><LI>To create a new read/write volume, use the <B>-name</B> argument to
-specify a volume name that does not already exist in the Volume Location
-Database (VLDB), and the <B>-server</B> and <B>-partition</B>
-arguments to specify the new volume's site. It is best to omit the
-<B>-id</B> argument so that the Volume Location (VL) Server allocates a
-volume ID automatically. Do not include the <B>-overwrite</B>
-argument, because there is no existing volume to overwrite.
-<P><LI>To overwrite an existing volume at its current site, specify its name and
-site with the <B>-name</B>, <B>-server</B>, and <B>-partition</B>
-arguments. The volume retains its current volume ID number unless the
-<B>-id</B> argument is provided. Specify the value <B>f</B> or
-<B>i</B> for the <B>-overwrite</B> argument to indicate whether the
-dump file is full or incremental, respectively.
-<P><LI>To overwrite an existing volume and move it to a new site, specify its
-name and the new site with the <B>-name</B>, <B>-server</B>, and
-<B>-partition</B> arguments. The volume retains its current volume
-ID number unless the <B>-id</B> argument is provided. The volume is
-removed from its original site. Specify the value <B>f</B> for the
-<B>-overwrite</B> 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).
-</UL>
-<P>If the volume named by the <B>-name</B> argument already exists and the
-<B>-overwrite</B> argument is omitted, the command interpreter produces
-the following prompt:
-<P>
-<PRE> Do you want to do a full/incremental restore or abort? [fia](a):
-
-</PRE>
-<P>Respond by entering one of the following values:
-<UL>
-<P><LI><B>f</B> if restoring a full dump file
-<P><LI><B>i</B> if restoring an incremental dump file
-<P><LI><B>a</B> or <<B>Return</B>> to cancel the restore operation
-</UL>
-<P><STRONG>Cautions</STRONG>
-<P>If the <B>-file</B> 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
-<B>-overwrite</B> argument if overwriting an existing volume.
-<P><STRONG>Options</STRONG>
-<DL>
-<P><DT><B>-server
-</B><DD>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
-the introductory reference page for the <B>vos</B> command suite.
-<P><DT><B>-partition
-</B><DD>Identifies the partition (on the file server machine specified by the
-<B>-server</B> argument) onto which to restore the volume. Provide
-the partition's complete name with preceding slash (for example,
-<B>/vicepa</B>) or use one of the three acceptable abbreviated
-forms. For details, see the introductory reference page for the
-<B>vos</B> command suite.
-<P><DT><B>-name
-</B><DD>Specifies the name under which to restore the volume. It can be up
-to 22 characters long, but cannot end with a <B>.readonly</B> or
-<B>.backup</B> extension. If the volume already exists, it
-is overwritten subject to the value of the <B>-overwrite</B>
-argument.
-<P><DT><B>-file
-</B><DD>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.
-<P><DT><B>-id
-</B><DD>Specifies the volume ID number to assign to the restored volume.
-<P><DT><B>-overwrite
-</B><DD>Specifies which type of dump file is being restored when overwriting an
-existing volume. Provide one of the following values:
-<UL>
-<P><LI><B>a</B> to terminate the restore operation.
-<P><LI><B>f</B> if restoring a full dump file.
-<P><LI><B>i</B> if restoring an incremental dump file. This value is
-not acceptable if the <B>-server</B> and <B>-partition</B> arguments
-do not indicate the volume's current site.
-</UL>
-<P>
-<P>This argument is mandatory if the <B>-file</B> argument is not
-provided.
-<P><DT><B>-cell
-</B><DD>Names the cell in which to run the command. Do not combine this
-argument with the <B>-localauth</B> flag. For more details, see the
-introductory <B>vos</B> reference page.
-<P><DT><B>-noauth
-</B><DD>Assigns the unprivileged identity <B>anonymous</B> to the
-issuer. Do not combine this flag with the <B>-localauth</B>
-flag. For more details, see the introductory <B>vos</B> reference
-page.
-<P><DT><B>-localauth
-</B><DD>Constructs a server ticket using a key from the local
-<B>/usr/afs/etc/KeyFile</B> file. The <B>vos</B> command
-interpreter presents it to the Volume Server and Volume Location Server during
-mutual authentication. Do not combine this flag with the
-<B>-cell</B> argument or <B>-noauth</B> flag. For more details,
-see the introductory <B>vos</B> reference page.
-<P><DT><B>-verbose
-</B><DD>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.
-<P><DT><B>-help
-</B><DD>Prints the online help for this command. All other valid options
-are ignored.
-</DL>
-<P><STRONG>Examples</STRONG>
-<P>The following command restores the contents of the dump file
-<B>/afs/abc.com/common/dumps/terry.dump</B> to the
-<B>/vicepc</B> partition on the file server machine
-<B>fs3.abc.com</B>. The restored volume is named
-<B>user.terry</B>.
-<PRE> % <B>cd /afs/abc.com/common/dumps</B>
-
- % <B>vos restore -file terry.dump -server fs3.abc.com -partition c</B> \
- <B>-name user.terry</B>
-
-</PRE>
-<P><STRONG>Privilege Required</STRONG>
-<P>The issuer must be listed in the <B>/usr/afs/etc/UserList</B> file on
-the machine specified with the <B>-server</B> argument and on each
-database server machine. If the <B>-localauth</B> flag is included,
-the issuer must instead be logged on to a server machine as the local
-superuser <B>root</B>.
