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