#
# Configuration file for BackupPC.
#
# DESCRIPTION
#
#   This is the main configuration file for BackupPC.
#
#   This file must be valid perl source, so make sure the punctuation,
#   quotes, and other syntax are valid.
#
#   This file is read by BackupPC at startup, when a HUP (-1) signal
#   is sent to BackupPC and also at each wakeup time whenever the
#   modification time of this file changes.
#
#   The configuration parameters are divided into four general groups.
#   The first group (general server configuration) provides general
#   configuration for BackupPC.  The next two groups describe what
#   to backup, when to do it, and how long to keep it.  The fourth
#   group are settings for the CGI http interface.
#
#   Configuration settings can also be specified on a per-PC basis.
#   Simply put the relevant settings in a config.pl file in the
#   PC's backup directory (ie: in __TOPDIR__/pc/hostName).
#   All configuration settings in the second, third and fourth
#   groups can be overridden by the per-PC config.pl file.

###########################################################################
#
# Host name on which the BackupPC server is running.
#
$Conf{ServerHost} = '';

#
# TCP port number on which the BackupPC server listens for and accepts
# connections.  Normally this should be disabled (set to -1).  The TCP
# port is only needed if apache runs on a different machine from BackupPC.
# In that case, set this to any spare port number over 1024 (eg: 2359).
# If you enable the TCP port, make sure you set $Conf{ServerMesgSecret}
# too!
#
$Conf{ServerPort} = -1;

#
# Shared secret to make the TCP port secure.  Set this to a hard to guess
# string if you enable the TCP port (ie: $Conf{ServerPort} > 0).
#
# To avoid possible attacks via the TCP socket interface, every client
# message is protected by an MD5 digest. The MD5 digest includes four
# items:
#   - a seed that is sent to the client when the connection opens
#   - a sequence number that increments for each message
#   - a shared secret that is stored in $Conf{ServerMesgSecret}
#   - the message itself.
#
# The message is sent in plain text preceded by the MD5 digest.  A
# snooper can see the plain-text seed sent by BackupPC and plain-text
# message from the client, but cannot construct a valid MD5 digest since
# the secret $Conf{ServerMesgSecret} is unknown.  A replay attack is
# not possible since the seed changes on a per-connection and
# per-message basis.
#

# Times at which we wake up, check all the PCs, and schedule necessary
# backups.  Times are measured in hours since midnight.  Can be
# fractional if necessary (eg: 4.25 means 4:15am).
#
# If the hosts you are backing up are always connected to the network
# you might have only one or two wakeups each night.  This will keep
# the backup activity after hours.  On the other hand, if you are backing
# up laptops that are only intermittently connected to the network you
# will want to have frequent wakeups (eg: hourly) to maximized the chance
# that each laptop is backed up.

# any Smb share or device mount point.
#
# Note also that you can also use $Conf{BackupFilesOnly} to specify

# Whether incremental backups are filled.  "Filling" means that the

# full dump.  Prior to v1.03 all incremental backups were filled.
# In v1.4.0 and later the default is off.
#
# BackupPC, and the cgi interface in particular, do the right thing on
# un-filled incremental backups.  It will correctly display the merged
# incremental backup with the most recent filled backup, giving the
# un-filled incremental backups a filled appearance.  That means it
# invisible to the user whether incremental dumps are filled or not.
#
# Filling backups takes a little extra disk space, and it does cost
# some extra disk activity for filling, and later removal.  Filling
# is no longer useful, since file mangling and compression doesn't
# make a filled backup very useful. It's likely the filling option
# will be removed from future versions: filling will be delegated to
# the display and extraction of backup data.
#
# If filling is off, BackupPC makes sure that the oldest backup is
# a full, otherwise the following incremental backups will be
# incomplete.  This might mean an extra full backup has to be

#
# This can be set to a string, an array of strings, or, in the case

# (the share name is the key).  If this is set to just a string or

#
# The exact behavior is determined by the underlying transport program,
# smbclient or tar.  For smbclient the exlclude file list is passed into
# the X option.  Simple shell wild-cards using "*" or "?" are allowed.
#
# For tar, if the exclude file contains a "/" it is assumed to be anchored
# at the start of the string.  Since all the tar paths start with "./",
# BackupPC prepends a "." if the exclude file starts with a "/".  Note
# that GNU tar version >= 1.3.7 is required for the exclude option to
# work correctly.  For linux or unix machines it is recommended to add
# "/proc" to $Conf{BackupFilesExclude}.
#
# Examples:
#    $Conf{BackupFilesExclude} = '/temp';

#
# To allow for periodic rebooting of a PC or other brief periods when a
# PC is not on the network, a number of consecutive bad pings is allowed
# before the good ping count is reset. This parameter is
# $Conf{BlackoutBadPingLimit}.
#
# Note that bad and good pings don't occur with the same interval. If a
# machine is always on the network, it will only be pinged roughly once
# every $Conf{IncrPeriod} (eg: once per day). So a setting for
# $Conf{BlackoutGoodCnt} of 7 means it will take around 7 days for a
# machine to be subject to blackout. On the other hand, if a ping is
# failed, it will be retried roughly every time BackupPC wakes up, eg,
# every one or two hours. So a setting for $Conf{BlackoutBadPingLimit} of
# 3 means that the PC will lose its blackout status after 3-6 hours of
# unavailability.
#
# To disable the blackout feature set $Conf{BlackoutGoodCnt} to a negative

# Note that GNU tar has several methods for specifying incremental backups,

#
#   --newer-mtime $incrDate+
#          This causes a file to be included if the modification time is

#          But changes in the ownership or modes will not qualify the
#          file to be included in an incremental.
#
#   --newer=$incrDate+
#          This causes the file to be included if any attribute of the
#          file is later than $incrDate, meaning either attributes or
#          the modification time.  This is the default method.  Do
#          not use --atime-preserve in $Conf{TarClientCmd} above,
#          otherwise resetting the atime (access time) counts as an
#          attribute change, meaning the file will always be included
#          in each new incremental dump.
