How to find early adopters and promote an open source application?

Question

For myself, I saw a need for efficient backup compression (much stronger than the usual .tar.gz due to deduplication). Even asked at the toaster. I did not find ready-made simple solutions, if there was something, it was very complicated, but I wanted simplicity - something like tar, not much more complicated. A simple utility. As a result, I wrote hashget . On deduplication, it "compresses" up to 0.5% of the original volume (1Gb to 5 Mb) on average for real-life data. When restoring, everything duplicated is restored from the network, everything unique is taken from the archive.
For example:

• A freshly installed virtual machine (its file system) on Debian is compressed like this up to 0.5%.
  
• You can index any package from the network yourself (say, wordpress), and then the files from it will also be compressed almost to zero. Including own packages, even in the internal network.
  
• You can index your own backups and conveniently implement a scheme with incremental / differential backups (and planned "obsolescence" of backups - if we plan to store a backup for 1 month, then after 1 month new backups will not rely on it)
  

It seems to me that the thing turned out to be very useful. If you pay for backups and this amount is noticeable to you, then hashget saves money. If you pay a small amount (for example, store on glacier), then thanks to hashget you can put much more into this amount (for example, store daily backups, not monthly ones. It's more convenient!). For VPS hosters, this is a great opportunity to make super-cheap backups of thousands of the same type of client machines.
But now there is a question - where and how to "advertise" it? There is no monetization in the project, everything is open-source, purely for self-realization. But I want people to know, try it, and someone started using it.
