One way you could get around this is to make it so only 1 job can run
at a time for a particular client. This will allow the full backup to
complete and the incremental queued to not actually start until such
job is completed.

But I'd have to agree, what are you backing up that is taking more
than two days? I hope you say you've got terabytes of data streaming
along or there is something else you should be worried about.
