[Duplicity-talk] --skip-same-content: Option to skip files whose content hasn't changed

[Elifarley Callado Coelho Cruz]

It would be nice to have an option to skip files which had their modification time changed without any changes to their content.

The algorithm could be something like:

- if mtime hasn't changed, skip

- compare the current file checksum against its last recorded checksum. Skip if they are the same

Would it be easy to implement? Which source files would I probably need to change?

Thanks,
