After running into some problems with some rsync scripts recently, I discovered that in Mac OS 15.4, Apple switched its built-in rsync command from standard rsync to the BSD project’s clone, openrsync. It is apparently not 100% compatible, because my backup and deploy scripts that use it were failing.

I use rsync for backups, site deployments, and other purposes where I need to sync two folders. It took a little while to figure out, but has been great for those purposes since. Every once in a while, though, I run into issues with it. Recently, I set up an rsync script to back up most of the files on my entire computer. Since this takes a while and the computer is actively running during the backup, things can change while it is still running. This can lead to some errors like “rsync warning: some files vanished before they could be transferred”. Even though this is a warning, and the sync works perfectly fine, it returns a non-zero exit code. This caused my script to stop and thus the rest of the backup activity didn’t finish.
