> I'd frequently upload 100GB+ files to OpenStack object storage (Swift), but have run
into trouble with tools that don't retry as it can be tough to do such a large transfer without
any network hiccup. I'm currently using the official python-swiftclient since it has retry
logic (see https://github.com/openstack/python-swiftclient/blob/master/swiftclient/client.py),
but I like that libcloud works with other providers such as S3 and Azure as well. The python-swiftclient
has an exponential backoff where it sleeps first 1 second, then 2, then 4, up to a max of
64 seconds between retries (1 and 64 are the min and max, but are configurable). It would
be great to see a similar logic in libcloud.
