Re: [Duplicity-talk] Restarting from wrong place

[Kenneth Loafman]

The B2 backend was rewritten in 0.7.15 to use the B2 API and not the web interface.  It's considerably faster and supports the progress indicator.

Some questions:

 - Has the backup size increased since you last ran a full backup?

 - What is the volume size you use (default is 200MB)? 

I'm guessing that, as the number of volumes increased, then B2 truncated the list being returned when querying for the list of files.  If I'm right, then it will repeat each time.

One thing to try, double your volume size, say 200MB to 400MB, start a new backup, and that should keep it from happening for a long while (just a workaround).

Please answer back and let me know if that works around the problem.

...Thanks,

...Ken

I just upgraded to 0.7.16 and see the same behavior.
