Solaris 11 running with VxFS running Standard FS backup taking more backup than estimated

[kdilli]

We are taking full backup for Server Solaris 11 Veritas Cluster Server ,we selected inclusion list manually ,total backup as per du -sh should be 4 TB but it takes 15 TB for full backup 4 days to complete ,witn 70mbp through put 

Please advise what should have gone wrong ,checked restore it has ran as per inclusion list .

If you list the files in the backup images, what's the excess of data ?

I am bit puzzled about the statement "inclusion list manually". Usually you specify what to backup in the policy, then exclude what you don't need via a exclude_list, if you then have excluded too much, you can then include it again.

What kind of filesystems are you backing up? Are they LOFS?

Are you using non-global zones?
