We attempted to do this where I work using Sun Trunking v1.3 in order 
to increase the speed between our backup server and our data 
warehouse, which holds over 4 TB of data.  Sun Trunking will only 
work for increasing backup speeds if you are backing up multiple 
servers simultaneously.  If you are trying to increase speed just to 
back up one primary system, it will not work because all of the 
options in Sun Trunking are still based on MAC address - one trunk 
per MAC.  (Sun's engineers confirmed this for me.)  So, if you're 
looking to increase the speed between one server and your backup 
server, Sun Trunking will not do anything.

The only thing that I could do given our particular configuration is 
split the work between two "hosts" (two network interfaces on both 
the backup server and data warehouse on different subnets) and create 
two policies with two different host names (both being different 
interfaces on the same server) to run simultaneously.  It might be a 
bit confusing during a restore, not that we need to do that 
frequently, but it's decreased our backup time by about 40%.  That 
alone is worth the unorthodox method that I used.
