What do you mean the 'the wakeuptime?   Wakeuptime should be a list of
times to do the scheduling, not necessarily the backup runs, and the
first time in the list is when backuppc_nightly runs to do
housekeeping and remove expired backups.

This still doesn't make any sense to me.  Are you sure the server date
is correct?  Maybe it thinks it is a weekend.

Nothing wrong, but the per-client configs can override the global
settings so you should at least look at the merged view from the
client configuration page to make sure it isn't different.

Most servers would work better with 4 or fewer concurrent backups -
completing the overall run faster - or perhaps even 2.

This should be a one-time thing to make the first backup start in your
backup window and stay there until the goodcount takes effect.

Your problem is that your blackout is not working, which I don't
understand.  You should be able to set different blackout periods in
the per-pc settings - but the wakeup list is global.   Maybe you
should try putting wakeups back to the default to see if that is what
is breaking your setup.

Yes, you set how often the fulls run or leave the default weekly
setting, then set a count of how many of those to retain. When that
number is exceeded, the oldest is deleted from the pc directory, then
a later backuppc_nightly run will remove the pool items whose link
count is down to 1 (not linked in any backup).  The disk space isn't
released until the pool files are removed.
