Re: [Duplicity-talk] Does duplicity resume?

[Kenneth Loafman]

Could work either way.  If we kept the checkpoint files on the local
machine, and resumed from that machine, overhead would be reduced.

A possibly better way to do it would be after N volumes, making sure to
complete the current input file.  Could just dump the state, the current
manifest, and the current sigtar, into temp files.  Resume could then be
done from the last state.

Hmmm, this is sounding plausible.  But, I need more coffee... there's
entirely too much blood in my caffeine stream at the moment.
