vi /etc/box/bbackupd.conf

Uncomment the ExtendedLogging line...

It would be nice to know.

So add a config line:

   PipeActionsToProcess = /path/to/utility

When it starts to sync, it runs this utility. When it does something 
interesting, it writes a line to stdin which describes what it did.

Maybe not a bad idea, and probably wouldn't take too long to implement.
