The backup volume's name is the same as the read/write source's with the addition of the \f(CW\*(C`.backup\*(C'\fR extension. Its volume \s-1ID\s0 number is the one allocated for it in the Volume Location Database (\s-1VLDB\s0) when the read/write source was created with the \fBvos create\fR command. If a backup version already exists, the new clone replaces it. .PP To create a backup version of multiple volumes, use the \fBvos backupsys\fR command. .SH "OPTIONS" .IX Header "OPTIONS" .IP "\fB\-id\fR <\fIvolume name or \s-1ID\s0\fR>" 4 .IX Item "-id " Specifies either the complete name or volume \s-1ID\s0 number of the read/write source volume. .IP "\fB\-cell\fR <\fIcell name\fR>" 4 .IX Item "-cell " Names the cell in which to run the command. Do not combine this argument with the \fB\-localauth\fR flag. For more details, see \fIvos\fR\|(1). .IP "\fB\-noauth\fR" 4 .IX Item "-noauth" Assigns the unprivileged identity anonymous to the issuer. Do not combine this flag with the \fB\-localauth\fR flag. For more details, see \fIvos\fR\|(1). .IP "\fB\-localauth\fR" 4 .IX Item "-localauth" Constructs a server ticket using a key from the local \&\fI/usr/afs/etc/KeyFile\fR file. The \fBvos\fR command interpreter presents it to the Volume Server and Volume Location Server during mutual authentication. Do not combine this flag with the \fB\-cell\fR argument or \&\fB\-noauth\fR flag. For more details, see \fIvos\fR\|(1). .IP "\fB\-verbose\fR" 4 .IX Item "-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. .IP "\fB\-encrypt\fR" 4 .IX Item "-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. .IP "\fB\-noresolve\fR" 4 .IX Item "-noresolve" Shows all servers as \s-1IP\s0 addresses instead of the \s-1DNS\s0 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. .IP "\fB\-help\fR" 4 .IX Item "-help" Prints the online help for this command. All other valid options are ignored. .SH "OUTPUT" .IX Header "OUTPUT" The following message confirms that the command succeeded: .PP .Vb 1 \& Created backup volume for I .Ve .SH "EXAMPLES" .IX Header "EXAMPLES" The following example creates a backup version of the volume \&\f(CW\*(C`user.smith\*(C'\fR. .PP .Vb 2 \& % vos backup user.smith \& Created backup volume for user.smith .Ve .SH "PRIVILEGE REQUIRED" .IX Header "PRIVILEGE REQUIRED" The issuer must be listed in the \fI/usr/afs/etc/UserList\fR file on the machine specified with the \fB\-server\fR argument and on each database server machine. If the \fB\-localauth\fR flag is included, the issuer must instead be logged on to a server machine as the local superuser \f(CW\*(C`root\*(C'\fR. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fIvos\fR\|(1), \&\fIvos_backupsys\fR\|(1) .SH "COPYRIGHT" .IX Header "COPYRIGHT" \&\s-1IBM\s0 Corporation 2000.
