Rsync-like downloads over adb?

NOTE: I asked a similar question here several days ago, but I was told to re-post it to "Stack Exchange Software Recommendations", which I did.
Now, I posted this current question to "Stack Exchange Software Recommendations", but I was told to re-post it here.
I hope this current question indeed will now be accepted here.

I know that I can use adb from my desktop computer to take a backup of my sdcard ...

adb pull /sdcard/ .

This downloads everything from my sdcard to the specified directory on my desktop machine. However, I'm wondering if there is some way to download in an rsync-like manner: i.e., only downloading and updating files that have actually changed between my device's sdcard and the directory on the desktop machine.

Or is there perhaps a non-adb-based way to do this?

Also, I want to initiate this from the desktop machine, not the Android device.

Any ideas?

PS: This is an Android-10 device, a OnePlus 7Pro (GM-1917) running OOS 10.3.2. However, the answer to my question is probably unrelated to that, since it has to do more with adb than the android device itself.

Thanks in advance.
