Re: [Duplicity-talk] Notice for S3/GCS Users

I am still trying to get 0.8.23 running on Mac OS.  I moved the dependency from boto to boto3 and it build and ran the local tests.  BUT when I tried to use s3 it mentioned that botocore was missing?

Maybe the changed syntax will fix this but I somehow doubt it.  AFAICT I need to install botocore as separate from boto3?

Note: I am using fink as my package manager for installing duplicity.

Hi all,

for those struggling with the changed S3 behavior in duplicity/boto3 regarding the --s3-endpoint-url, I thought I'd give an example. I took my some trial and error to figure out what needed to go where.

So if previously (before 0.8.23) you were using a destination like:
duplicity --s3-use-new-style --s3-european-buckets /mypath s3://s3.eu-west-1.amazonaws.com/my-bucket-name/

the new syntax (0.8.23+) should be something like:
duplicity --s3-use-new-style --s3-european-buckets --s3-endpoint-url https://s3.eu-west-1.amazonaws.com/ /mypath s3://my-bucket-name/

Hopefully that will save someone some headaches! :-)

We made the following changes and released them in 0.8.23.dev15 development version on GitLab, Launchpad PPA, Snapcraft (edge), and PyPi.  If you use the release/stable version, please use this for planning purposes.  This will be part of 0.8.23 in a month or so.

Since some users use the dev version, here are the changes:
  • boto3 backend is now default s3:// backend. It does not support s3:/// but needs --s3-endpoint-url instead
  • boto3 supports --s3-unencrypted-connection option now
  • boto backend now usable via boto+s3:// or boto+gs:// only
  • boto's s3+http:// scheme was removed, use boto+s3:// instead
  • boto supports --s3-endpoint-url. --s3-use-deep-archive options now
  • changes are documented in man page
I would suggest that if/when this breaks things, please consult the man page.  There are a bunch of much needed updates that will see you through.
