Re: [Duplicity-talk] Diagnosing "blob exists error" with Azure backend

[Kenneth Loafman]

Hi, 

Perhaps you do need to remove the last incremental and try again.  Simply do:

    # rm *<date-string>*

where date-string is the start date of the increment.

...Thanks,

hmm. i'm not sure that a fluke in azure client or module justifies a permanent workaround in duplicity. but surely, if you want to get familiar with the backend[1] and contribute a reasonable workaround, we will appreciate your contribution.
