At the risk of sounding uncaring, it's not Bacula's job to enforce disk
quota policies.  The answer to this problem is to allocate a per-client
storage area for data that will be backed up, with strict quotas on the
filesystem.  Alternately, if setting disk quotas is not an option, one
could implement a run-before-job task on the client that checks how much
data is in the directory (or directories) to be backed up, and
administratively fails the backup if the allocated 10GB backup quota is
exceeded.

This is not a Bacula problem, it's a general IT administration problem,
and adding a feature to Bacula that intentionally truncates backups is
not the way to solve it.
