=head1 NAME vos restore - Converts an ASCII dump file into an AFS volume =head1 SYNOPSIS B B<-server> > B<-partition> > B<-name> > [B<-file> >] [B<-id> >] [B<-overwrite> (abort | full | incremental)] [B<-cell> >] [B<-noauth>] [B<-localauth>] [-verbose] [B<-help>] B B<-s> > B<-p> > B<-na> > [B<-f> >] [B<-i> >] [B<-o> (a | f | i)] [B<-c> >] [B<-no>] [B<-l>] [B<-v>] [B<-h>] =head1 DESCRIPTION The B command converts a volume dump file previously created with the B command from ASCII into the volume format appropriate for the machine type indicated by the B<-server> argument, and restores it as a read/write volume to the partition named by the B<-partition> argument on that machine. The Volume Server assigns the volume name indicated with the B<-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 C field in the output from the B and B commands.) Use the B<-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. =over 4 =item * To create a new read/write volume, use the B<-name> argument to specify a volume name that does not already exist in the Volume Location Database (VLDB), and the B<-server> and B<-partition> arguments to specify the new volume's site. It is best to omit the B<-id> argument so that the Volume Location (VL) Server allocates a volume ID automatically. Do not include the B<-overwrite> argument, because there is no existing volume to overwrite. =item * To overwrite an existing volume at its current site, specify its name and site with the B<-name>, B<-server>, and B<-partition> arguments. The volume retains its current volume ID number unless the B<-id> argument is provided. Specify the value C or C for the B<-overwrite> argument to indicate whether the dump file is full or incremental, respectively. =item * To overwrite an existing volume and move it to a new site, specify its name and the new site with the B<-name>, B<-server>, and B<-partition> arguments. The volume retains its current volume ID number unless the B<-id> argument is provided. The volume is removed from its original site. Specify the value C for the B<-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). =back If the volume named by the B<-name> argument already exists and the B<-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: =over 4 =item * C if restoring a full dump file =item * C if restoring an incremental dump file =item * C or Return to cancel the restore operation =back =head1 CAUTIONS If the B<-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 B<-overwrite> argument if overwriting an existing volume. =head1 OPTIONS =over 4 =item B<-server> > 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 L. =item B<-partition> > Identifies the partition (on the file server machine specified by the B<-server> argument) onto which to restore the volume. Provide the partition's complete name with preceding slash (for example, F) or use one of the three acceptable abbreviated forms. For details, see L. =item B<-name> > Specifies the name under which to restore the volume. It can be up to 22 characters long, but cannot end with a C<.readonly> or C<.backup> extension. If the volume already exists, it is overwritten subject to the value of the B<-overwrite> argument. =item B<-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. =item B<-id> > Specifies the volume ID number to assign to the restored volume. =item B<-overwrite> (a | f | i) Specifies which type of dump file is being restored when overwriting an existing volume. Provide one of the following values: =over 4 =item * C to terminate the restore operation. =item * C if restoring a full dump file. =item * C if restoring an incremental dump file. This value is not acceptable if the B<-server> and B<-partition> arguments do not indicate the volume's current site. =back This argument is mandatory if the B<-file> argument is not provided. =item B<-cell> > Names the cell in which to run the command. Do not combine this argument with the B<-localauth> flag. For more details, see L. =item B<-noauth> Assigns the unprivileged identity C to the issuer. Do not combine this flag with the B<-localauth> flag. For more details, see L. =item B<-localauth> Constructs a server ticket using a key from the local F file. The 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> argument or B<-noauth> flag. For more details, see L. =item B<-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. =item B<-help> Prints the online help for this command. All other valid options are ignored. =back =head1 EXAMPLES The following command restores the contents of the dump file F to the F partition on the file server machine C. The restored volume is named C. % cd /afs/abc.com/common/dumps % vos restore -file terry.dump -server fs3.abc.com -partition c \ -name user.terry =head1 PRIVILEGE REQUIRED The issuer must be listed in the F file on the machine specified with the B<-server> argument and on each database server machine. If the B<-localauth> flag is included, the issuer must instead be logged on to a server machine as the local superuser C. =head1 SEE ALSO L, L, L, L =head1 COPYRIGHT IBM Corporation 2000.
