What is the alternative to rsync for detecting changes in place?

Question

Backup

Good afternoon.
There is a task to make a backup: there must be a copy of my home folder on another machine. History is not needed, just a copy.
My home folder is about 80 Gb. The remote machine is quite slow with a slow disk.
I solved the problem with rsync. But it works very slowly. Tens of minutes with almost no change. He spends most of his time, of course, scanning a remote folder and comparing.
The question is, can I make it cache this data locally? So that he (or his alternative) locally monitors changes, and only sends changes to a remote machine. Let even without segment-by-segment comparison of files. In principle, writing such a script in java or FP is not difficult, but maybe there is something ready-made, easy and standard?
Linux OS, access to the remote machine only via ssh.
Thank you.

Have you tried Rsnapshot? Under the hood, of course, he has the same Rsync, but at least I didn’t notice such brakes in myself.
