I am looking at duply and duplicity currently to mirror one bucket to another but it looks like I may be running in to a brick wall?
So far I have been able to get things working backing up local directories to an S3 bucket, that part works great. My real problem is that I am trying to create an S3 bucket backup by backing essentially mirroring two buckets.
When I attempt to run the duply tool I receive the following output:
sudo duply test backup

As you can see duply/duplicity is expecting a local file path as the source. I can produce configs if it is helpful in diagnosing the issue.
Is there any way to get duply/duplicity to run a backup agains one S3 bucket as a source to another S3 target? If not, what tools are capable of syncing two S3 buckets?
