310 size (your mileage may vary). Specify the compression level (0 turns
311 off compression, and 1 to 9 represent good/fastest to best/slowest).
312 The recommended values are 0 (off) or 3 (reasonable compression and speed).
313 Increasing the compression level to 5 will use around 20% more cpu time
314 and give perhaps 2-3% more compression.

320 BackupPC can compress pool files, but it needs the Compress::Zlib
321 package installed (see www.cpan.org). Compression will provide around a
322 40% reduction in pool size, at the expense of cpu time. You can leave
323 compression off and run BackupPC without compression, in which case you
324 should leave the compression level at 0 (which means off). You could
325 install Compress::Zlib and turn compression on later, but read the
326 documentation first about how to do this. Or the better choice is

334 BackupPC now supports pool file compression. Since you are upgrading
335 BackupPC you probably have existing uncompressed backups. You have
336 several choices if you want to turn on compression. You can run
337 the script BackupPC_compressPool to convert everything to compressed
338 form. Or you can simply turn on compression, so that new backups
339 will be compressed. This will increase the pool storage requirement,
340 since both uncompressed and compressed copies of files will be stored.
341 But eventually the old uncompressed backups will expire, recovering
342 the pool storage. Please see the documentation for more details.
344 If you are not sure what to do, leave the Compression Level at 0,
345 which disables compression. You can always read the documentation
346 and turn it on later.
350 $Conf{CompressLevel} = 0;
353 BackupPC now supports pool file compression, but it needs the
354 Compress::Zlib module (see www.cpan.org). For now, leave
355 the compression level set at 0 to disable compression. If you
356 want you can install Compress::Zlib and turn compression on.

742 - Browse through the config file, $Conf{TopDir}/conf/config.pl,
743 and make sure all the settings are correct. In particular, you
744 will need to set the smb share password and user name, backup
745 policies and check the email message headers and bodies.
747 - Edit the list of hosts to backup in $Conf{TopDir}/conf/hosts.
749 - Read the documentation in $Conf{InstallDir}/doc/BackupPC.html.
750 Please pay special attention to the security section.
752 - Verify that the CGI script BackupPC_Admin runs correctly. You might
753 need to change the permissions or group ownership of BackupPC_Admin.
755 - BackupPC should be ready to start. Don't forget to run it
756 as user $Conf{BackupPCUser}! The installation also contains an
757 init.d/backuppc script that can be copied to /etc/init.d
758 so that BackupPC can auto-start on boot. This will also enable
759 administrative users to start the server from the CGI interface.

965 configure.pl [options]
969 configure.pl is a script that is used to install or upgrade a BackupPC
970 installation. It is usually run interactively without arguments. It
971 also supports a batch mode where all the options can be specified
972 via the command-line.
974 For upgrading BackupPC you need to make sure that BackupPC is not
975 running prior to running BackupPC.
977 Typically configure.pl needs to run as the super user (root).
985 Run configure.pl in batch mode. configure.pl will run without
986 prompting the user. The other command-line options are used
987 to specify the settings that the user is usually prompted for.
989 =item B<--bin-path PROG=PATH>
991 Specify the path for various external programs that BackupPC
992 uses. Several --bin-path options may be specified. configure.pl
993 usually finds sensible defaults based on searching the PATH.
998 where PROG is one of perl, tar, smbclient, nmblookup, rsync, ping,
999 df, ssh, sendmail, hostname, split, par2, cat, gzip, bzip2 and
1000 PATH is that full path to that program.
1004 --bin-path cat=/bin/cat --bin-path bzip2=/home/user/bzip2
1006 =item B<--config-path CONFIG_PATH>
1008 Path to the existing config.pl configuration file for BackupPC.
1009 This option should be specified for batch upgrades to an
1010 existing installation. The option should be omitted when
1011 doing a batch new install.
1013 =item B<--cgi-dir CGI_DIR>
1015 Path to Apache's cgi-bin directory where the BackupPC_Admin
1016 script will be installed. This option only needs to be
1017 specified for a batch new install.
1019 =item B<--data-dir DATA_DIR>
1021 Path to the BackupPC data directory. This is where all the backup
1022 data is stored, and it should be on a large file system. This option
1023 only needs to be specified for a batch new install.
1027 --data-dir /data/BackupPC
1029 =item B<--dest-dir DEST_DIR>
1031 An optional prefix to apply to all installation directories.
1032 Usually this is not needed, but certain auto-installers like
1033 to stage an install in a temporary directory, and then copy
1034 the files to their real destination. This option can be used
1035 to specify the temporary directory prefix. Note that if you
1036 specify this option, BackupPC won't run correctly if you try
1037 to run it from below the --dest-dir directory, since all the
1038 paths are set assuming BackupPC is installed in the intended
1043 Print a brief help message and exits.
1045 =item B<--hostname HOSTNAME>
1047 Host name (this machine's name) on which BackupPC is being installed.
1048 This option only needs to be specified for a batch new install.
1050 =item B<--html-dir HTML_DIR>
1052 Path to an Apache html directory where various BackupPC image files
1053 and the CSS files will be installed. This is typically a directory
1054 below Apache's DocumentRoot directory. This option only needs to be
1055 specified for a batch new install.
1059 --html-dir /usr/local/apache/htdocs/BackupPC
1061 =item B<--html-dir-url URL>
1063 The URL (without http://hostname) required to access the BackupPC html
1064 directory specified with the --html-dir option. This option only needs
1065 to be specified for a batch new install.
1069 --html-dir-url /BackupPC
1071 =item B<--install-dir INSTALL_DIR>
1073 Installation directory for BackupPC scripts, libraries, and
1074 documentation. This option only needs to be specified for a
1079 --install-dir /usr/local/BackupPC
1083 Prints the manual page and exits.
1085 =item B<--uid-ignore>
1087 configure.pl verifies that the script is being run as the super user
1088 (root). Without the --uid-ignore option, in batch mode the script will
1089 exit with an error if not run as the super user, and in interactive mode
1090 the user will be prompted. Specifying this option will cause the script
1091 to continue even if the user id is not root.
1095 For a standard interactive install, run without arguments:
1099 For a batch new install you need to specify answers to all the
1100 questions that are normally prompted:
1104 --cgi-dir /var/www/cgi-bin/BackupPC \
1105 --data-dir /data/BackupPC \
1107 --html-dir /var/www/html/BackupPC \
1108 --html-dir-url /BackupPC \
1109 --install-dir /usr/local/BackupPC
1111 For a batch upgrade, you only need to specify the path to the
1114 configure.pl --batch --config-path /data/BackupPC/conf/config.pl
