[Duplicity-talk] Batch option of SCP?

[numa]

I am trying to incorporate duplicity into a batch upload of a very large 
server volume to another volume.  It works perfectly, except... duplicity 
splits the volumes into these 50MB files, which is fine, actually it's kinda 
slick, what I dislike is entering a password each time. 

There is a good chance I am approaching what I am trying to do in a stupid 
way, so any advice is appreciated.  The volume I am transfering is 10gigs.  
Thanks.  Kris
