Could you inform as to me which API you are using and whether you are using it in a WebApp environment? The majority of 51Degrees APIs support automatic updates, on start the server will check for updated data files and download them.

This can be used to replace large files with pointers to remote storage. This is a nice solution as we've found versioning large files can make the repository quite sluggish. Here's a blog about our experience if you're interested https://51degrees.com/blog/51degree...ant-update
