366 The recommended values are 0 (off) or 3 (reasonable compression and speed).

377 compression off and run BackupPC without compression, in which case you
378 should leave the compression level at 0 (which means off). You could
379 install Compress::Zlib and turn compression on later, but read the

388 BackupPC now supports pool file compression. Since you are upgrading
389 BackupPC you probably have existing uncompressed backups. You have
390 several choices if you want to turn on compression. You can run
391 the script BackupPC_compressPool to convert everything to compressed
392 form. Or you can simply turn on compression, so that new backups
393 will be compressed. This will increase the pool storage requirement,
394 since both uncompressed and compressed copies of files will be stored.
395 But eventually the old uncompressed backups will expire, recovering
396 the pool storage. Please see the documentation for more details.
398 If you are not sure what to do, leave the Compression Level at 0,
399 which disables compression. You can always read the documentation
400 and turn it on later.

407 BackupPC now supports pool file compression, but it needs the
408 Compress::Zlib module (see www.cpan.org). For now, leave
409 the compression level set at 0 to disable compression. If you
410 want you can install Compress::Zlib and turn compression on.

770 - Browse through the config file, $Conf{ConfDir}/config.pl,

772 will need to set the smb share password and user name, backup
773 policies and check the email message headers and bodies.
775 - Edit the list of hosts to backup in $Conf{ConfDir}/hosts.
777 - Read the documentation in $Conf{InstallDir}/doc/BackupPC.html.
778 Please pay special attention to the security section.
780 - Verify that the CGI script BackupPC_Admin runs correctly. You might
781 need to change the permissions or group ownership of BackupPC_Admin.
783 - BackupPC should be ready to start. Don't forget to run it
784 as user $Conf{BackupPCUser}! The installation also contains an
785 init.d/backuppc script that can be copied to /etc/init.d
786 so that BackupPC can auto-start on boot. This will also enable
787 administrative users to start the server from the CGI interface.

1013 configure.pl [options]
1017 configure.pl is a script that is used to install or upgrade a BackupPC
1018 installation. It is usually run interactively without arguments. It
1019 also supports a batch mode where all the options can be specified
1020 via the command-line.
1022 For upgrading BackupPC you need to make sure that BackupPC is not
1023 running prior to running BackupPC.
1025 Typically configure.pl needs to run as the super user (root).
1033 Run configure.pl in batch mode. configure.pl will run without
1034 prompting the user. The other command-line options are used
1035 to specify the settings that the user is usually prompted for.
1037 =item B<--backuppc-user=USER>
1039 Specify the BackupPC user name that owns all the BackupPC
1040 files and runs the BackupPC programs. Default is backuppc.
1042 =item B<--bin-path PROG=PATH>
1044 Specify the path for various external programs that BackupPC
1045 uses. Several --bin-path options may be specified. configure.pl
1046 usually finds sensible defaults based on searching the PATH.
1049 --bin-path PROG=PATH
1051 where PROG is one of perl, tar, smbclient, nmblookup, rsync, ping,
1052 df, ssh, sendmail, hostname, split, par2, cat, gzip, bzip2 and
1053 PATH is that full path to that program.
1057 --bin-path cat=/bin/cat --bin-path bzip2=/home/user/bzip2
1059 =item B<--compress-level=N>
1061 Set the configuration compression level to N. Default is 3
1062 if Compress::Zlib is installed.
1064 =item B<--config-path CONFIG_PATH>
1066 Path to the existing config.pl configuration file for BackupPC.
1067 This option should be specified for batch upgrades to an
1068 existing installation. The option should be omitted when
1069 doing a batch new install.
1071 =item B<--cgi-dir CGI_DIR>
1073 Path to Apache's cgi-bin directory where the BackupPC_Admin
1074 script will be installed. This option only needs to be
1075 specified for a batch new install.
1077 =item B<--data-dir DATA_DIR>
1079 Path to the BackupPC data directory. This is where all the backup
1080 data is stored, and it should be on a large file system. This option
1081 only needs to be specified for a batch new install.
1085 --data-dir /data/BackupPC
1087 =item B<--dest-dir DEST_DIR>
1089 An optional prefix to apply to all installation directories.
1090 Usually this is not needed, but certain auto-installers like
1091 to stage an install in a temporary directory, and then copy
1092 the files to their real destination. This option can be used
1093 to specify the temporary directory prefix. Note that if you
1094 specify this option, BackupPC won't run correctly if you try
1095 to run it from below the --dest-dir directory, since all the
1096 paths are set assuming BackupPC is installed in the intended
1101 Use locations specified by the Filesystem Hierarchy Standard
1102 for installing BackupPC. This is enabled by default for new
1103 installatios. To use the pre-3.0 installation locations,
1108 Print a brief help message and exits.
1110 =item B<--hostname HOSTNAME>
1112 Host name (this machine's name) on which BackupPC is being installed.
1113 This option only needs to be specified for a batch new install.
1115 =item B<--html-dir HTML_DIR>
1117 Path to an Apache html directory where various BackupPC image files
1118 and the CSS files will be installed. This is typically a directory
1119 below Apache's DocumentRoot directory. This option only needs to be
1120 specified for a batch new install.
1124 --html-dir /usr/local/apache/htdocs/BackupPC
1126 =item B<--html-dir-url URL>
1128 The URL (without http://hostname) required to access the BackupPC html
1129 directory specified with the --html-dir option. This option only needs
1130 to be specified for a batch new install.
1134 --html-dir-url /BackupPC
1136 =item B<--install-dir INSTALL_DIR>
1138 Installation directory for BackupPC scripts, libraries, and
1139 documentation. This option only needs to be specified for a
1144 --install-dir /usr/local/BackupPC
1148 Prints the manual page and exits.
1150 =item B<--set-perms>
1152 When installing files and creating directories, chown them to
1153 the BackupPC user and chmod them too. This is enabled by default.
1154 To disable (for example, if staging a destination directory)
1155 then specify --no-set-perms.
1157 =item B<--uid-ignore>
1159 configure.pl verifies that the script is being run as the super user
1160 (root). Without the --uid-ignore option, in batch mode the script will
1161 exit with an error if not run as the super user, and in interactive mode
1162 the user will be prompted. Specifying this option will cause the script
1163 to continue even if the user id is not root.
1167 For a standard interactive install, run without arguments:
1171 For a batch new install you need to specify answers to all the
1172 questions that are normally prompted:
1176 --cgi-dir /var/www/cgi-bin/BackupPC \
1177 --data-dir /data/BackupPC \
1179 --html-dir /var/www/html/BackupPC \
1180 --html-dir-url /BackupPC \
1181 --install-dir /usr/local/BackupPC
1183 For a batch upgrade, you only need to specify the path to the
1186 configure.pl --batch --config-path /data/BackupPC/conf/config.pl
