VirtualFull backups be a partial solution to your problem.   We have a
laptop which we get very short backup time windows for -- never enough time
to run a full backup.  Instead, we run incrementals (takes about 20% of the
time) and then run virtualfull backups to consolidate them.  We never need
to run real full backups.

Deduplication of this sort is not available as far as I know.

I suggested a feature some time back which might help.  I'm not sure if
there's enough interest in it though.  You can see this in the bacula
projects file:

http://bacula.git.sourceforge.net/git/gitweb.cgi?p=bacula/bacula;a=blob_plain;f=bacula/projects;hb=HEAD

Item n:   Implement a Migration job type that will create a reverse
          incremental (or decremental) backup from two existing full backups.
