The backup addvolentry command adds a volume entry definition to the
existing volume set named by the -name argument. A volume entry
definition can match one or more volumes, depending on the combination of
the -server, -partition, and -volumes arguments.
For the -server and -partition arguments, provide either
The name of one machine or partition.
The metacharacter expression .* (period and asterisk), which matches every
machine name or partition name in the Volume Location Database (VLDB).
For the -volumes argument, specify a combination of alphanumeric
characters and one or more metacharacters to wildcard part or all of the
volume name. OPTIONS lists the acceptable metacharacters.
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.
-name <volume set name>
Names the volume set to which to add this volume entry definition. The
volume set must already exist (use the backup addvolset command to
-server <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
"fs1.abc.com") or the metacharacter expression ".*" (period and
asterisk), which matches all machine names in the VLDB.
-partition <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
"/vicepa") or the metacharacter expression ".*" (period and asterisk),
which matches all partition names.
-volumes <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
The period matches any single character.
The asterisk matches zero or more instances of the preceding character.
Combine it with any other alphanumeric character or metacharacter.
Square brackets around a list of characters match a single instance of any
of the characters, but no other characters; for example, "[abc]" matches
a single "a" or "b" or "c", but not "d" or "A". This expression can
be combined with the asterisk.
The caret, when used as the first character in a square-bracketed set,
designates a match with any single character except the characters that
follow it; for example, "[^a]" matches any single character except
lowercase "a". This expression can be combined with the asterisk.
A backslash preceding any of the metacharacters in this list makes it
match its literal value only. For example, the expression "\." (backslash
and period) matches a single period, "\*" a single asterisk, and "\\" a
single backslash. Such expressions can be combined with the asterisk (for
example, "\.*" matches any number of periods).
Perhaps the most common metacharacter expression is the period followed by
an asterisk (".*"). 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 -server and -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 "user" and
ends with "backup":
Constructs a server ticket using a key from the local
/etc/openafs/server/KeyFile file. The backup command interpreter presents
it to the Backup Server, Volume Server and VL Server during mutual
authentication. Do not combine this flag with the -cell argument. For
more details, see backup(8).
-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 backup(8).
Prints the online help for this command. All other valid options are
The following command adds a volume entry to the volume set called
"sys". The entry matches all volumes on any machine or partition whose
names begin with the string "sun4x_56" followed by a period:
backup> addvolentry sys .* .* sun4x_56\..*
The following command adds a volume entry to the volume set called "fs2",
to match all volumes on the /vicepb partition of file server machine
"fs2.abc.com". Because it is issued at the shell prompt, double quotes
surround the metacharacters in the -volumes argument. (The command is
shown here on two lines only for legibility reasons.)
The chapter in the IBMAFS Administration Guide about configuring the
AFS Backup System presents additional examples as well as advice on
The issuer must be listed in the /etc/openafs/server/UserList file on every
machine where the Backup Server is running, or must be logged onto a
server machine as the local superuser "root" if the -localauth flag is
