This might be a bit late, but I'm playing around with base jobs to do 
deduplicaton of my backups. It might be worth a look. From what I gather, it 
works like this:

1) You manually run a job to backup your files. The job should contain 
something like this:
Name = "Base_Job"
Level = base

2) You modify your regular backup job to include the "Base" parameter. 
Something like:
Name = "Backup_OS_1"
Base = "Backup_OS_1", "Base_Job"
Accurate = yes

Now when Backup_OS_1 job runs, it's will compare files with those already in 
the Base_Job and won't back them up again if it finds a match. I think the way 
a "match" is defined is by using "Accurate" in the "Backup_OS_1" job and 
modifying "Accurate" in the fileset definition to change the default behaviour 
of how matches are performed.
