0.6 is the deprecated code tree, reasonably stable, not receiving any updates, 
maybe some major bugfixes if at all. 
0.7 has some experimental changes but is based on 0.6, so there is no reason 
for you not to use it. simply do some tests first. make backups to the backend 
of your choice, with the amount of data you expect to backup later. establish a 
full/incr routine. check if purging works as expected. most importantly try to 
restore after a while and verify the result.

if all that works, you have reason to trust your data to duplicity or any other 
backup software for that matter.

if not, it might be a bug introduced in 0.7, try 0.6.25 as a workaround.

you seem to have to create containers for that
