+# There are two special values for $Conf{FullPeriod}:
+#
+# -1 Don't do any regular backups on this machine. Manually
+# requested backups (via the CGI interface) will still occur.
+#
+# -2 Don't do any backups on this machine. Manually requested
+# backups (via the CGI interface) will be ignored.
+#
+# These special settings are useful for a client that is no longer
+# being backed up (eg: a retired machine), but you wish to keep the
+# last backups available for browsing or restoring to other machines.
+#
+# Also, you might create a virtual client (by setting $Conf{ClientNameAlias})
+# for restoring to a DVD or permanent media and you would set
+# $Conf{FullPeriod} to -2 so that it is never backed up.
