correct

you would have to make sure that only /one/ instance of duplicity is running 
adding data to the repository. that's crucial! incomplete chains are simply 
ignored, so you could end up with incrementals basing themselves on the wrong 
previous incremental (as they used the one before that). 
i could imagine it'd take longer to process 10GB if your system is under load.

you should probably research other ways to backup encrypted that frequently.

i would suggest you to find a way to 
A) generate local diffs
B) encrypt & upload these in a second step
