Indeed, 'git backfill' is intended to assist with downloading the blobs that were not selected in a blobless partial clone. > I’ve never used blob/treeless. I don't believe that 'git backfill' is optimized for treeless clones. Treeless clones are not intended for "refilling" as downloading missing trees is particularly expensive. ... And regarding the original thought for "we should have an option for doing blobless clones by default" the current way to do that is to use 'scalar clone' which is shipped with Git already. When Scalar was originally contributed to Git, it was partly to enable users to opt-in to a version of 'git clone' that changes behavior with best practices and advanced features as they are developed. This is in contrast to 'git clone' which needs to remain backwards compatible, so any new features need to be selected with an option or config setting. But there was always the possibility that the feedback from having 'scalar clone' available could lead to a future builtin of the form 'git big-clone' that adds similar optimizations for large repos. (My opinion is that 'scalar clone' _is_ this 'git big-clone' but maybe it is not discoverable enough.) Thanks, -Stolee
