: If you use Bitbucket Data Center , it has built-in support for S3. It acts as a proxy: clients talk to Bitbucket, and Bitbucket transparently streams the files from S3.
If you want to tailor this setup to your specific environment, let me know:
Git is the undisputed standard for version control, but it was fundamentally designed to track text-based source code. When software projects begin incorporating massive binary assets—such as game textures, data science datasets, video clips, or compiled machine learning models—standard Git repositories quickly degrade. Performance plummets, cloning takes hours, and storage costs skyrocket.
What you plan to deploy. The average file size and types your team works with.
If you already own an S1 or S2 license, upgrading to S3 will only cost you the price difference. The base price for an S3 license is (British Pounds), though the exact price can vary depending on your country's VAT rate. lfs s3 account

The following protocol outlines how to configure a secure, self-hosted Git LFS S3 environment utilizing a custom transfer agent system on a local development workstation. Step 1: Prepare the Amazon S3 Infrastructure
Have you already migrated your LFS to S3? What authentication server are you using? Let me know in the comments below.
Run the server application. It will begin listening for incoming connections (typically on port 8080 ). Step 4: Configuring the Local Git Repository : If you use Bitbucket Data Center ,
"Version": "2012-10-17", "Statement": [ "Sid": "GitLFSS3Access", "Effect": "Allow", "Action": [ "s3:PutObject", "s3:GetObject", "s3:DeleteObject", "s3:ListBucket" ], "Resource": [ "arn:aws:s3:::company-git-lfs-storage", "arn:aws:s3:::company-git-lfs-storage/*" ] ] Use code with caution. Save the and Secret Access Key securely. Step 2: Deploy an Open-Source Git LFS Server
This approach utilizes an open-source, self-hosted LFS server (such as lfs-test-server , giftless , or rudolfs ) deployed on an EC2 instance, AWS Fargate, or a private server. The server implements the official Git LFS API. It authenticates client requests, generates AWS S3 Pre-signed URLs, and passes them back to the client. The local Git client then uploads or downloads the binary payload directly to or from S3. 2. Standalone Git LFS Custom Transfer Agents
: Never expose your LFS bridge endpoint over unencrypted HTTP. Because the system transmits authorization tokens and proprietary business data payloads, SSL/TLS termination is mandatory.
Next, define which file formats your LFS system should track and intercept.For example, to route all Photoshop documents and ZIP archives: The average file size and types your team works with
An LFS S3 account refers to a storage setup where Git LFS data is routed away from your standard Git provider's default storage and directed into an AWS S3 bucket or an S3-compatible object storage API (like MinIO, Backblaze B2, or Cloudflare R2). How It Works
Your code stays in your normal Git host. Your large files stay in your S3 account.
: Storage costs accumulate over time as old, unused binary versions linger in your history. Configure an S3 Lifecycle Policy on your bucket to automatically transition older, deprecated LFS objects to colder storage tiers like Glacier Flexible Retrieval, or delete unreferenced objects entirely.
During the execution of git push , your configured custom transfer agent intercepts the LFS pipeline, reads your local AWS profile credentials, and uploads sample_video.mp4 directly to your S3 bucket path. You can verify the file is there by checking your AWS S3 console. Best Practices for S3 LFS Administration
