One-way backup/distribution with Pulse/Syncthing

Hi, I’d like to use syncthing as an incremental backup solution.

I have a setup where a machine store newly generated files and that machine is limited in it’s storage… Those files are transmitted/archived to a central storage server (a few of those, to be precise) which end up serving as the main storage for those files. When files are deleted from the original machine (where again, space is limited), the deletions are not “forwarded” to the archving machine.

I’d like to be able to use pulse/syncthing to accomplish something like this (basically like rsync without specifying --delete*), and I’m pretty sure the current folder features don’t allow this to happen.

I hope I’m describing this correctly, and I’d love to hear what other people have to say about this.
