[Duplicity-talk] Duplicity does not restart after interrupted transmission

[Scott Hannahs]

Folks,

I have a backup script that runs unattended every night.  It backs up 3 
directories using rsync and a temp directory on the local machine.  I have been 
getting an error for the last week or so that keeps two of the directories from 
backing up.  It is an "Operation not permitted" error but it is not clear to me 
what operation is not being permitted by whom.

The file exists and I have full read/write permissions to it.
% ls -l

contents of the manifest file are correct?

Any advice would be appreciated.
