Hi there,

I have Backuppc V4 rpm installation on Centos8 and I am experiencing
troubles with blackout periods.
I would like this server to perform backups during daytime only but I
cannot apply the desired behaviour.
At the end of this message you can find my $Conf{WakeupSchedule} and
$Conf{BlackoutPeriods}.
I have not defined blackout periods per hosts and thus only server-wide
periods should be applied. I have of course reloaded configuration
multiple times but no changes.
For example, one host started a backup at 1:00 AM tuesday and another
20:36 monday. This is in contrast with the second blackout period I have
defined.

Am I doing something wrong?
Probably. The extract below is verbatim, from config.pl. Does it help?

# PCs that are always or often on the network can be backed up after
# hours, to reduce PC, network and server load during working hours. For
# each PC a count of consecutive good pings is maintained. Once a PC has
# at least $Conf{BlackoutGoodCnt} consecutive good pings it is subject
# to "blackout" and not backed up during hours and days specified by
# $Conf{BlackoutPeriods}.
#
# 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
# value. A value of 0 will make all machines subject to blackout. But
# if you don't want to do any backups during the day it would be easier
# to just set $Conf{WakeupSchedule} to a restricted schedule.
#
$Conf{BlackoutBadPingLimit} = 3;
$Conf{BlackoutGoodCnt} = 7;

Something seems a bit odd in the part of your post below:
...
3,
'3.6',
4,
$Conf{WakeupSchedule} = [
1,
'1.6',
2,
'2.6',
...
];
...
Is it a cut'n'paste error?
Anyway in your case it's probably easier to set $Conf{BlackoutGoodCnt}
to 0 as described above and just rely on the wakeup schedule.
