Hi Les,
 
I tried using the black out option but somehow i do see backups running during prime time (i.e. 8am to 6pm).
 
Could you assist with the sample options i should set or change so that I can run backups at 8pm with weekly/monthly full and retention for 1 year?
 
Regards,
Prem.

The server is designed to handle a larger number of backups by
controlling the scheduling internally.

It works best to think in terms of when _not_ to do backups and set
your blackout periods for that, letting backuppc do its work anytime
outside of those times.  However, if you do the initial setup or force
a full at approximately the time you want backups to happen, the
'approximately daily' scheduling will stay fairly close to that timing
as long as the machines are running.

There isn't a real concept of monthy and yearly, but with the pooling
scheme there is not much overhead if you need to keep some extra
copies due to approximations with days/weeks.

And if you really need fine-grained control, you can use cron:
