For comparison, I think GitHub just have a cap of 100MB on any single individual file, plus:
> We recommend repositories remain small, ideally less than 1 GB, and less than 5 GB is strongly recommended. Smaller repositories are faster to clone and easier to work with and maintain. If your repository excessively impacts our infrastructure, you might receive an email from GitHub Support asking you to take corrective action. We try to be flexible, especially with large projects that have many collaborators, and will work with you to find a resolution whenever possible.
Which is a bit wishy-washy, but sounds like there's room for discretion / exceptions to be made there rather than a hard cap at 5GB.
