#INSTALL GIT LFS FORCE PACK LARGE FILES INSTALL#
Git LFS is a Git extension that you only need to install once. Please check the documentation for your Git host system. To use Git LFS server-side, you need a Git LFS aware host such as GitHub, GitHub Enterprise, Bitbucket Cloud, Bitbucket Server, hosted GitLab and self-hosted GitLab.ĭepending on your Git server system, Git LFS is either enabled by default or you might need to enable Git LFS manually. git clone and git pull operations are faster because Git only downloads the versions of large files referenced by commits you check out. You can use git checkout, git add and git commit as normal, there is no change to your normal Git workflow. In your local working copy you only see your actual file content. When you checkout a commit that contains Git LFS pointers, they are replaced with files from your local Git LFS cache, or downloaded from the remote Git LFS store. When you push new commits to the server, any Git LFS files referenced by the newly pushed commits are transferred from your local Git LFS cache to the remote Git LFS store tied to your Git repository. When you add a file via git add, Git LFS replaces its contents with a pointer, and writes the file contents to a local Git LFS cache. For your normal Git operations, you never get to see these pointer files as Git LFS handles them automatically: These pointer files act as references to the actual files which are stored somewhere else. Git LFS handles large files by replacing them with tiny pointer files. This helps tremendously when managing our Excel workbook repositories: When you do a git clone or git pull, Git only downloads the head version so that you can get to work straight away (instead of having to wait for all those old versions that you are probably not interested in anyway at that point). Git LFS reduces the impact of large files by downloading them lazily: Files, that are tracked by LFS, are only downloaded when you check out a specific version instead of downloading every file version that ever existed during the clone or fetch process. Git Large File Storage (LFS) is an open-source Git extension developed by Atlassian, GitHub, and other contributors.

This figure is exaggerated as Git uses file compression, but it gives you an idea of how much data you have to download if you (or someone else) performs a git clone or git fetch and it will only grow bigger as time goes by. For repositories containing large files and/or long commit histories, this clone process can take a long time, as every file version that ever existed has to be downloaded.įor Excel workbook repositories, it is only a question of time before this becomes a real problem: If your repository contains one 5MB-sized workbook which you commit once every business day, you end up with roughly 250 x 5MB = 1.3GB worth of workbook versions after one year. As a distributed version control system, Git always copies down the entire repository history to the client when you do a git clone or git fetch.
