.SH DESCRIPTION
This program reads the client-side configuration file and runs
(eventually a part of) a full backup of all files and directories
specified in the configuration file or on the commandline. It is
recommended to setup everything in the configuration file and run
this command without any arguments (same applies for incr_backup).
If files and/or directories are supplied on the commandline, those
specified in the configuration file are overridden. Furthermore
the program then behaves slightly different: If backup parts are
configured, they are ignored. The timestamp, that is evaluated
during incremental backup to determine, whether files have been
modified, is not changed. This behaviour reflects the assumption,
that supplying files or directories on the commandline is done
for testing or other temporary purposes. Modifying the timestamp
would confuse the normal regularly running backup mechanism. In
these temporary cases the -a option should make sense, see below
for details. Be also aware of the -C option's meaning. If the name
of a file is preceded with -r, the contents of the file is stored,
but not the characteristics of the inode. This is useful for
saving raw devices. By default, processing is always turned off.
Using -R forces processing of the contents. Preceding a directory
name with -m the recursive descent into this directory is limited
to the filesystem, where the directory resides.
The names of the files and directories, that are stored, are
written into logfiles, that comprise of the indexfile-part (-I)
and the current total backup counter. This counter is incremented
each time a full backup (part 1) starts. A minimum information
required to restore after a hard crash having lost everything is
piped into the startup-info-program (-i). 
Whether only a part of a full backup is run depends on the setting
of the parameter NumBackupParts (See: afclient.conf(8)).
If the configuration
file is not supplied explicitly, then it is searched for in the
@clientconfdir@ and @clientlibdir@, and if not found there the files
/etc/buclient.conf, /etc/afbuclient.conf, /etc/afclient.conf and
/etc/afbackup/client.conf are tried.
Commandline options generally override configuration file settings.
Every option described below (except -c) has a corresponding
entry in the configuration file, but there are more possible
settings in the config file.
.PP
.TP
.B -a
Append mode. Do not increment the total backup
counter. (See -N)
.TP
.B {+-}B
Perform per-file processing on the stored files
(+B) or not (-B) (See: -F)
.TP
.B -b <initprog>
Run the given program before attempting a backup.
If the command returns an exit status unequal
to 0, no backup is performed (see: -e). Not to
be mixed up with option -i
.TP
.B -C <rootdir>
Change to the given directory before starting the
backup climbing down into the directories to be
stored
.TP
.B -c <configfile> 
A different configuration file to use
.TP
.B -D <skip-dirs>
A list of directory name patterns separated by
whitespace to ignore for backup. Several must be
put into quotes (See: -F and -X)
.TP 
.B -d              
Detach from the terminal when starting
.TP
.B -e <exitprog>
Run the specified program after finishing. If the
command comprises of several words separated by
whitespace, it must be put into quotes (See: -i)
.TP
.B -F <skip-files>
A list of filename patterns separated by whitespace
to ignore for backup. Several must be put into
quotes (See: -D and -X)
.TP
.B -f <fs-types>
A list of filesystem types, separated by whitespace
and/or commas. The type names can be prefixed
with a plus, what is identical with no prefix,
with a dash - or a slash / . No prefix or a plus
means, that only files in filesystems of the
given type are saved, no others. A minus means,
files in a filesystem of the named type are not
saved, nonetheless such filesystems are traversed
to search for filesystems of other types probably
mounted underneath. The slash means, that such
filesystems are not even entered or traversed. If
the - or + prefix is used, no space is allowed
between option -f and it's argument, e.g. -f-nfs
.TP
.B -G
To request a new cartridge. If the current writing
position is already at the beginning of a new or
reused tape, nothing happens
.TP
.B -h <backuphosts>
The names of the hosts, where a backup server side
lives. The list can be separated by commas and/or
whitespace. If whitespace is present, quotes are
necessary. The hosts are tested for service availability.
If a backup server is not ready, the next one is
tried. If all are busy, the program waits for a
minute and tries again
.TP
.B -I <idx-prefix>
The first part of the filename, the names of the
stored files and directories are written to. The
current total backup number is appended (that
increments each start of a full backup). If these
files undergo processing, .z is appended
.TP
.B -i <info-prog>
The command to save startup information. A minimum
information to recover from a hard crash is piped
into this program (at stdin). If the command
comprises of several words, it must be put into
quotes. Not to be mixed up with option -b
.TP
.B -k <file>
Use the contents of the given file as encryption
key for authenticating to the server
.TP
.B {+-}L
Process the filename list files (+L) or not (-L)
(See: -I)
.TP
.B -l <logfile>
Write loggings into the given logfile. A dash -
means: no logging, only write to stderr
.TP
.B -M <server-message-config>
The configuration to output messages from the server,
that normally are sent only via mail to a maintainer.
The first word consisting of the letters b r v and c
tells, whether to output messages during backup,
restore, verify and copy-tape, respecively. The next
words must name the service name or port number of
the single stream servers, related to the option -P .
For each multi stream service configured with -P or
in the configuration file, the respective single
stream service must be given here
.TP
.B -N <num-idxes>
The number of filename list files, that is stored
over time. A new list is begun at each start of
a full backup (except -a is supplied)
.TP
.B -O <maxidxage>
The maximum age of the filename list files (== index
files) in days, that is stored. See also option
-N . A floating point number is allowed here
.TP
.B -P <portnos>
The port numbers, that are tried to connect at the
servers. They must be supplied positionally according
to the configured or (with the -h option) given
backup servers. The list may be separated by whitespace
and/or commas. If whitespace is present, quotes are
necessary
.TP
.B -S <cartsets>
The cartridge sets to use, where 
.I <cartsets> 
is a number of a valid cartridge set on the appropriate
server side. Default is 1. These must be supplied
positionally according
to the configured or (with the -h option) given
backup servers. The list may be separated by whitespace
and/or commas. If whitespace is present, quotes are
necessary
.TP
.B -s <noproc>
A list of filename patterns, that no processing is
attempted on, what can save time significantly.
The list should always be enclosed in quotes
.TP
.B -V <var-dir>
The directory, where varying files are put
.TP
.B -W <identity>
Identify as <id> to the server. This is needed when
connecting a multi-stream server to distinguish
between the clients. Default is the official
hostname of the client. If the client should fake
to be a different one than it is in fact, this
