: When a team member clones the repo, Git downloads the light text pointers. Git LFS then fetches the heavy assets from the S3 bucket automatically. Why Route Git LFS to an S3 Bucket?
Add a large asset to your repository workspace to verify that file payloads bypass standard Git remote targets and stream smoothly into the S3 bucket: lfs s3 account
When developers rewrite Git history, switch branches, or delete files, old binary assets remain stored in your S3 bucket forever. Run git lfs prune locally to clear out your local cache. To clean your remote S3 account, implement an object lifecycle policy on the S3 bucket to move older versions to cheaper storage or use specialized scripting to match active Git tree pointers against your S3 object inventory.
