rsync is the tar of network transfers. It is extremely useful, but has too many options, so one ends up memorizing a few use cases and carefully sticking to them.

I still have PTSD from the time I played with the options and made the mistake of swapping source and destination, where the destination was a blank disk.

--dry-run is a useful safety net when trying new combinations of options. That, and the fact it'll never delete unless you specifically give it an option with "delete" in its name.

haha, you say rsync is the tar of network transfers, but have you ever considered using tar for network transfers?

Time a 'tar | nc' sometime to a remove server, it'll blow away the rsync time.

you are not wrong, but you are missing the argument
