Use
estimate level=Incremental
Or
estimate level=Differential
>From the manual:
Using this command, you can get an idea how many files will
be backed up, or if you are unsure about your Include statements in
your FileSet, you can test them without doing an actual backup. The
default is to assume a Full backup. However, you can override this
by specifying a level=Incremental or level=Differential on the
command line. A Job name must be specified or you will be prompted
for one, and optionally a Client and FileSet may be specified on the
command line. It then contacts the client which computes the number
of files and bytes that would be backed up. Please note that this is an
estimate calculated from the number of blocks in the file rather than
by reading the actual bytes. As such, the estimated backup size will
generally be larger than an actual backup.

Estimates are full. It's in the manual, IIRC.
