Running backuppc 3.3.0-2+deb8u1 on Debian GNU/Linux 8.8 Jessie.
Used command
/usr/share/backuppc/bin/BackupPC_serverMesg backup 192.168.42.2 humppa
backuppc 1
to force full backup.
The request appears in the log but seems to have no effect.

The second request at 21:45 is from cron. I was expecting the backup to
start at next wakeup or when blackout period ends at the latest.
The backup for humppa finally starts at 01:48, but this is from normal
schedule.

I tried to force the full backup to run friday night, but seems the
serverMesg backup does not have any effect. I googled for old mailing
list entries, and found about serverMesg and the syntax it uses. I also
read this is the way backups should be started from command line, and
not using BackupPC_dump.
The reason I am trying to do this from cron is to correct the tendency
of the backup start times to creep forward. Eventually the full backups
start so late in the monday morning they are still running during
working hours. I remember I read about this in this mailing list
sometime previously, but did not find that list entry now that I tried
to do it myself.
