What do you mean by "cleanup the datafiles on the target server"?  Are 
you editing files on the target server?

If the target is not 100% different from the source, yes, keep it!  
Rsync will upload the differences of the two.  If 99% of the file is the 
same, you just saved 99% of your transfer time. :)

See timestamps and checksum in the manual to see what option you need to 
use in your schema.  Checksum may take some time with 3/4 TB of data :-/

So you want to update files and transfer new files?  How about:

rsync -e ssh -avz /source/data/files isk at target:/data/files

This command works over ssh (for encryption), uses an archive mode (see 
manual for details), spits out information verbosely, and compresses 
files during transfer to speed it up.  If you would like to watch it 
happen, add --progress for cool status view.
