=head1 DESCRIPTION
|
|
|
|
The B<backup addvolentry> command adds a volume entry definition to the
|
|
existing volume set named by the B<-name> argument. A volume entry
|
|
definition can match one or more volumes, depending on the combination of
|
|
the B<-server>, B<-partition>, and B<-volumes> arguments.
|
|
|
|
For the B<-server> and B<-partition> arguments, provide either
|
|
|
|
=over 4
|
|
|
|
=item *
|
|
|
|
The name of one machine or partition.
|
|
|
|
=item *
|
|
|
|
The metacharacter expression .* (period and asterisk), which matches every
|
|
machine name or partition name in the Volume Location Database (VLDB).
|
|
|
|
=back
|
|
|
|
For the B<-volumes> argument, specify a combination of alphanumeric
|
|
characters and one or more metacharacters to wildcard part or all of the
|
|
volume name. L</OPTIONS> lists the acceptable metacharacters.
|
|
|
|
=head1 CAUTIONS
|
|
|
|
It is best to issue this command in interactive mode. If issuing it at the
|
|
shell prompt, enclose any strings containing metacharacters in double
|
|
quotes, or escape the metacharacters with other delimiters, to prevent the
|
|
shell from interpreting them. Adding volume entries to a temporary volume
|
|
set is possible only within the interactive session in which the volume
|
|
set was created.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-name> <I<volume set name>>
|
|
|
|
Names the volume set to which to add this volume entry definition. The
|
|
volume set must already exist (use the B<backup addvolset> command to
|
|
create it).
|
|
|
|
=item B<-server> <I<machine name>>
|
|
|
|
Defines the set of one or more file server machines that house the volumes
|
|
in the volume entry. Provide either one fully-qualified hostname (such as
|
|
C<fs1.abc.com>) or the metacharacter expression C<.*> (period and
|
|
asterisk), which matches all machine names in the VLDB.
|
|
|
|
=item B<-partition> <I<partition name>>
|
|
|
|
Defines the set of one or more partitions that house the volumes in the
|
|
volume entry. Provide either one complete partition name (such as
|
|
C</vicepa>) or the metacharacter expression C<.*> (period and asterisk),
|
|
which matches all partition names.
|
|
|
|
=item B<-volumes> <I<volume name>>
|
|
|
|
Defines the set of one or more volumes included in the volume
|
|
entry. Specify the volumes by name, by using any combination of regular
|
|
alphanumeric characters and one or more of the following metacharacter
|
|
expressions:
|
|
|
|
=over 4
|
|
|
|
=item .
|
|
|
|
The period matches any single character.
|
|
|
|
=item *
|
|
|
|
The asterisk matches zero or more instances of the preceding character.
|
|
Combine it with any other alphanumeric character or metacharacter.
|
|
|
|
=item [ ]
|
|
|
|
Square brackets around a list of characters match a single instance of any
|
|
of the characters, but no other characters; for example, C<[abc]> matches
|
|
a single C<a> or C<b> or C<c>, but not C<d> or C<A>. This expression can
|
|
be combined with the asterisk.
|
|
|
|
=item ^
|
|
|
|
The caret, when used as the first character in a square-bracketed set,
|
|
designates a match with any single character I<except> the characters that
|
|
follow it; for example, C<[^a]> matches any single character except
|
|
lowercase C<a>. This expression can be combined with the asterisk.
|
|
|
|
=item \
|
|
|
|
A backslash preceding any of the metacharacters in this list makes it
|
|
match its literal value only. For example, the expression C<\.> (backslash
|
|
and period) matches a single period, C<\*> a single asterisk, and C<\\> a
|
|
single backslash. Such expressions can be combined with the asterisk (for
|
|
example, C<\.*> matches any number of periods).
|
|
|
|
=back
|
|
|
|
Perhaps the most common metacharacter expression is the period followed by
|
|
an asterisk (C<.*>). This expression matches any string of any length,
|
|
because the period matches any character and the asterisk means any number
|
|
of that character. As mentioned, it is the only acceptable metacharacter
|
|
expression for the B<-server> and B<-partition> arguments. In a volume
|
|
definition it can stand alone (in which case it matches every volume
|
|
listed in the VLDB), or can combine with regular characters. The following
|
|
example matches any volume name that begins with the string C<user> and
|
|
ends with C<backup>:
|
|
|
|
user.*backup
|
|
|
|
=item B<-localauth>
|
|
|
|
Constructs a server ticket using a key from the local
|
|
F</usr/afs/etc/KeyFile> file. The B<backup> command interpreter presents
|
|
it to the Backup Server, Volume Server and VL Server during mutual
|
|
authentication. Do not combine this flag with the B<-cell> argument. For
|
|
more details, see L<backup(8)>.
|
|
|
|
=item B<-cell> <I<cell name>>
|
|
|
|
Names the cell in which to run the command. Do not combine this argument
|
|
with the B<-localauth> flag. For more details, see L<backup(8)>.
|
|
|
|
=item B<-help>
|
|
|
|
Prints the online help for this command. All other valid options are
|
|
ignored.

|
|
=head1 EXAMPLES
|
|
|
|
The following command adds a volume entry to the volume set called
|
|
C<sys>. The entry matches all volumes on any machine or partition whose
|
|
names begin with the string C<sun4x_56> followed by a period:
|
|
|
|
backup> addvolentry sys .* .* sun4x_56\..*
|
|
|
|
The following command adds a volume entry to the volume set called C<fs2>,
|
|
to match all volumes on the F</vicepb> partition of file server machine
|
|
C<fs2.abc.com>. Because it is issued at the shell prompt, double quotes
|
|
surround the metacharacters in the B<-volumes> argument. (The command is
|
|
shown here on two lines only for legibility reasons.)
|
|
|
|
% backup addvolentry -name fs2 -server fs2.abc.com \
|
|
-partition /vicepb -volumes ".*"
|
|

The chapter in the I<OpenAFS Administration Guide> about configuring the
|
|
AFS Backup System presents additional examples as well as advice on
|
|
grouping volumes.
|
|
|
|
=head1 PRIVILEGE REQUIRED
|
|
|
|
The issuer must be listed in the F</usr/afs/etc/UserList> file on every
|
|
machine where the Backup Server is running, or must be logged onto a
|
|
server machine as the local superuser C<root> if the B<-localauth> flag is
|
|
included.
