194 the main data directory and read/execute permission on the install

197 The primary group for this user should also be chosen carefully.
198 By default the install directories will have group write permission.

249 BackupPC can compress pool files, providing around a 40% reduction in pool
250 size (your mileage may vary). Specify the compression level (0 turns
251 off compression, and 1 to 9 represent good/fastest to best/slowest).
252 The recommended values are 0 (off) or 3 (reasonable compression and speed).
253 Increasing the compression level to 5 will use around 20% more cpu time
254 and give perhaps 2-3% more compression.
257 } elsif ( $ConfigPath eq "" ) {
260 BackupPC can compress pool files, but it needs the Compress::Zlib
261 package installed (see www.cpan.org). Compression will provide around a
262 40% reduction in pool size, at the expense of cpu time. You can leave
263 compression off and run BackupPC without compression, in which case you
264 should leave the compression level at 0 (which means off). You could
265 install Compress::Zlib and turn compression on later, but read the
266 documentation first about how to do this. Or the better choice is
267 to quit, install Compress::Zlib, and re-run configure.pl.

274 BackupPC now supports pool file compression. Since you are upgrading
275 BackupPC you probably have existing uncompressed backups. You have
276 several choices if you want to turn on compression. You can run
277 the script BackupPC_compressPool to convert everything to compressed
278 form. Or you can simply turn on compression, so that new backups
279 will be compressed. This will increase the pool storage requirement,
280 since both uncompressed and compressed copies of files will be stored.
281 But eventually the old uncompressed backups will expire, recovering
282 the pool storage. Please see the documentation for more details.
284 If you are not sure what to do, leave the Compression Level at 0,
285 which disables compression. You can always read the documentation
286 and turn it on later.
290 $Conf{CompressLevel} = 0;
293 BackupPC now supports pool file compression, but it needs the
294 Compress::Zlib module (see www.cpan.org). For now, leave
295 the compression level set at 0 to disable compression. If you
296 want you can install Compress::Zlib and turn compression on.
297 Please see the documentation for more details about converting
298 old backups to compressed form.

647 - Browse through the config file, $Conf{TopDir}/conf/config.pl,
648 and make sure all the settings are correct. In particular, you
649 will need to set the smb share password and user name, backup
650 policies and check the email message headers and bodies.
652 - Edit the list of hosts to backup in $Conf{TopDir}/conf/hosts.
654 - Read the documentation in $Conf{InstallDir}/doc/BackupPC.html.
655 Please pay special attention to the security section.
657 - Verify that the CGI script BackupPC_Admin runs correctly. You might
658 need to change the permissions or group ownership of BackupPC_Admin.
660 - BackupPC should be ready to start. Don't forget to run it
661 as user $Conf{BackupPCUser}! The installation also contains an
662 init.d/backuppc script that can be copied to /etc/init.d
663 so that BackupPC can auto-start on boot. This will also enable
664 administrative users to start the server from the CGI interface.
