The simplest method would be something like this:

$Conf{FullKeepCnt} = [365];

This would give you every backup for the past 12 months... If this is
only accounting data, then I presume it is relatively small (as
opposed to user file shares and emails).

Don't be scared of keeping too many backups... they will always be
useful eventually. If you run out of space on the backup server, then
just add more :)

Of course, if you don't like that method, check the docs for the
command line to tell the system to run a specific type of backup, and
drop that into cron. Just set your backuppc *Period values to longer
than cron will do it.

Adam
