That’s honestly pretty small. When it says "it's not recommended to be used in multi-million user installations”
You are several orders of magnitude away from that. Well, three if you want to be technical about it.

If you want a backup server ready to go, rsync will probably work just fine for you, or as Adi have mentioned, a block-level replicator (though I suspect that is overkill) and dsync is likely to do exactly what you want. Yes, you have to keep an eye on it, but at your level It’s probably going to be solid (based on reading other’s experiences with it).

Of course, it is also easy to do it wrong, so careful reading of the documentation is critical, and testing your solution a coupe thousands times before you start relying on it.
