Yes its possible.

two ways.

1. DumpPostUserCmd (with a suitable script or command, but you'll likely 
need sudo to help out)

2. run a cron job to shutdown  backuppc at a specified time.
   if you know how long a backup should take then you can schedule 
accordingly. also you can use DumpPostUserCmd to say touch a file when 
its finished. In turn you have a separate script which polls for that 
file, if it finds it it issues the shutdwon command and removes the file.

But then how do you know when to start it back up?

WakeUp schedules and blackout periods should enable you to only do 
backups at specified times  and always have backuppc running. So i guess 
the real question should be what do you want to achieve?

As another example here's what i do in some cases.....

backuppc is on a removable drive that gets rotated weekly.
i modified the init script to mount the drive before starting backuppc 
and unmount after stopping backuppc.
i also stopped any automounting from occurring.
a cronjob runs at 7am to stop backuppc and unmount the drive.
a cronjob runs at 7pm to mount the drive and start backuppc
Why? because i only want backups to occur after hours. I know they will 
only take at most a few hours. And it gives the ordinary end user an 
easy way to remove the drives during the day when they want to swap them 
over for rotation. they simply power off the drive, unplug it and put 
the new one in and switch it on. At 7pm backuppc starts, mounting the 
new drive and normally kicks off a backup at 8pm, or the next WakeUp 
schedule.

Hope that helps,

Regards,

Les
