I am aware of the public photon-db files available at Index of /public/ that are generated weekly. The files themselves are quite large even when compressed and while the project I’m looking at doesn’t need weekly updates the update process itself is a bit slow due to the size. Is it possible to get a download of just the changes week by week?
No. It is technically not possible. (or, at least, I do not know a way to get the differences of two elasticsearch indices)

Hi, I’m reusing this post to ask a similar question.
Considering that there is no incremental download possible, do you know if there is a way to download the files with a bigger bandwidth ?
My download yesterday took 50 hours, at less than 1 Mb/s.
I know that some cloud providers provide more efficient download than through hosted web servers, e.g. through S3.
My servers are on Scaleway, and it would be great to reduce the download times without putting more weight on Graphhopper’s servers.
My use case is cartes.app, an alternative to Google Maps. We host our own Photon to avoid over-charging the demo server 
Thanks anyways for what you’re doing !
Also, note that it’s worse for the OpenSearch version, weighting 110 Go instead of 94 Go.
