364 size (your mileage may vary). Specify the compression level (0 turns
365 off compression, and 1 to 9 represent good/fastest to best/slowest).
366 The recommended values are 0 (off) or 3 (reasonable compression and speed).
367 Increasing the compression level to 5 will use around 20% more cpu time

374 BackupPC can compress pool files, but it needs the Compress::Zlib
375 package installed (see www.cpan.org). Compression will provide around a
376 40% reduction in pool size, at the expense of cpu time. You can leave
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.
404 $Conf{CompressLevel} = 0;
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.

412 old backups to compressed form.

805 Ok, it looks like we are finished. There are several more things you
808 - Browse through the config file, $Conf{ConfDir}/config.pl,
809 and make sure all the settings are correct. In particular, you
810 will need to set the smb share password and user name, backup
811 policies and check the email message headers and bodies.
813 - Edit the list of hosts to backup in $Conf{ConfDir}/hosts.
815 - Read the documentation in $Conf{InstallDir}/doc/BackupPC.html.
816 Please pay special attention to the security section.
818 - Verify that the CGI script BackupPC_Admin runs correctly. You might
819 need to change the permissions or group ownership of BackupPC_Admin.
821 - BackupPC should be ready to start. Don't forget to run it
822 as user $Conf{BackupPCUser}! The installation also contains an
823 init.d/backuppc script that can be copied to /etc/init.d
824 so that BackupPC can auto-start on boot. This will also enable
825 administrative users to start the server from the CGI interface.
831 if ( `$Conf{PerlPath} -V` =~ /uselargefiles=undef/ ) {
834 Warning: your perl, $Conf{PerlPath}, does not support large files.
835 This means BackupPC won't be able to backup files larger than 2GB.
836 To solve this problem you should build/install a new version of perl
837 with large file support enabled. Use
839 $Conf{PerlPath} -V | egrep uselargefiles
841 to check if perl has large file support (undef means no support).

1049 configure.pl [options]
1053 configure.pl is a script that is used to install or upgrade a BackupPC
1054 installation. It is usually run interactively without arguments. It
1055 also supports a batch mode where all the options can be specified
1056 via the command-line.
1058 For upgrading BackupPC you need to make sure that BackupPC is not
1059 running prior to running BackupPC.
1061 Typically configure.pl needs to run as the super user (root).
1069 Run configure.pl in batch mode. configure.pl will run without
1070 prompting the user. The other command-line options are used
1071 to specify the settings that the user is usually prompted for.
1073 =item B<--backuppc-user=USER>
1075 Specify the BackupPC user name that owns all the BackupPC
1076 files and runs the BackupPC programs. Default is backuppc.
1078 =item B<--bin-path PROG=PATH>
1080 Specify the path for various external programs that BackupPC
1081 uses. Several --bin-path options may be specified. configure.pl
1082 usually finds sensible defaults based on searching the PATH.
1085 --bin-path PROG=PATH
1087 where PROG is one of perl, tar, smbclient, nmblookup, rsync, ping,
1088 df, ssh, sendmail, hostname, split, par2, cat, gzip, bzip2 and
1089 PATH is that full path to that program.
1093 --bin-path cat=/bin/cat --bin-path bzip2=/home/user/bzip2
1095 =item B<--compress-level=N>
1097 Set the configuration compression level to N. Default is 3
1098 if Compress::Zlib is installed.
1100 =item B<--config-path CONFIG_PATH>
1102 Path to the existing config.pl configuration file for BackupPC.
1103 This option should be specified for batch upgrades to an
1104 existing installation. The option should be omitted when
1105 doing a batch new install.
1107 =item B<--cgi-dir CGI_DIR>
1109 Path to Apache's cgi-bin directory where the BackupPC_Admin
1110 script will be installed. This option only needs to be
1111 specified for a batch new install.
1113 =item B<--data-dir DATA_DIR>
1115 Path to the BackupPC data directory. This is where all the backup
1116 data is stored, and it should be on a large file system. This option
1117 only needs to be specified for a batch new install.
1121 --data-dir /data/BackupPC
1123 =item B<--dest-dir DEST_DIR>
1125 An optional prefix to apply to all installation directories.
1126 Usually this is not needed, but certain auto-installers like
1127 to stage an install in a temporary directory, and then copy
1128 the files to their real destination. This option can be used
1129 to specify the temporary directory prefix. Note that if you
1130 specify this option, BackupPC won't run correctly if you try
1131 to run it from below the --dest-dir directory, since all the
1132 paths are set assuming BackupPC is installed in the intended
1137 Use locations specified by the Filesystem Hierarchy Standard
1138 for installing BackupPC. This is enabled by default. To
1139 use the pre-3.0 installation locations, specify --no-fhs.
1143 Print a brief help message and exits.
1145 =item B<--hostname HOSTNAME>
1147 Host name (this machine's name) on which BackupPC is being installed.
1148 This option only needs to be specified for a batch new install.
1150 =item B<--html-dir HTML_DIR>
1152 Path to an Apache html directory where various BackupPC image files
1153 and the CSS files will be installed. This is typically a directory
1154 below Apache's DocumentRoot directory. This option only needs to be
1155 specified for a batch new install.
1159 --html-dir /usr/local/apache/htdocs/BackupPC
1161 =item B<--html-dir-url URL>
1163 The URL (without http://hostname) required to access the BackupPC html
1164 directory specified with the --html-dir option. This option only needs
1165 to be specified for a batch new install.
1169 --html-dir-url /BackupPC
1171 =item B<--install-dir INSTALL_DIR>
1173 Installation directory for BackupPC scripts, libraries, and
1174 documentation. This option only needs to be specified for a
1179 --install-dir /usr/local/BackupPC
1183 Prints the manual page and exits.
1185 =item B<--set-perms>
1187 When installing files and creating directories, chown them to
1188 the BackupPC user and chmod them too. This is enabled by default.
1189 To disable (for example, if staging a destination directory)
1190 then specify --no-set-perms.
1192 =item B<--uid-ignore>
1194 configure.pl verifies that the script is being run as the super user
1195 (root). Without the --uid-ignore option, in batch mode the script will
1196 exit with an error if not run as the super user, and in interactive mode
1197 the user will be prompted. Specifying this option will cause the script
1198 to continue even if the user id is not root.
1202 For a standard interactive install, run without arguments:
1206 For a batch new install you need to specify answers to all the
1207 questions that are normally prompted:
1211 --cgi-dir /var/www/cgi-bin/BackupPC \
1212 --data-dir /data/BackupPC \
1214 --html-dir /var/www/html/BackupPC \
1215 --html-dir-url /BackupPC \
1216 --install-dir /usr/local/BackupPC
1218 For a batch upgrade, you only need to specify the path to the
1221 configure.pl --batch --config-path /data/BackupPC/conf/config.pl
