Error trying use duplicity for backups

Question

I was asked to help with broken backup script on legacy system. There is a script file on server which should run hourly to put DB backup to Rackspace cloud. And here is the result.

what is the source of the problem and what is the way to fix it? As I can see there is a missing file on our backup storage so we cannot produce incremental backup. Am I right?

Answer 1

smells like the cf backend is broken. probably some changes in the cf API.

try to update to the latest duplicity 0.6.x or 0.7.x and retry.
