yeah, that’s what I was thinking, though 0.6 seems to not have made that 
request. Turns out, there’s the same stuff going on, whatever 0.7 does here:

The command I run is

duplicity collection-status --archive-dir '/var/.duply-cache' --name 
duply_zzz_local --encrypt-key XXXXXXXX --encrypt-key YYYYYYYY --sign-key 
XXXXXXXX --verbosity '9' --gpg-options '--pinentry-mode=loopback 
--compress-algo=bzip2 --bzip2-compress-level=9' --full-if-older-than 1W 
--volsize 200 'file:///path/to/zzz_local'

time’s output:

0.6: 0.41 real         0.28 user         0.03 sys
0.7: 71.01 real        37.57 user        23.71 sys

It’s a single chain, full backup has 3 volumes, one incremental with 1 volume 
and one incremental with 317 volumes.

Cheers,

Philip
