I think I have finally worked through and fixed the issues caused by Mac OS 15.4 switching from rsync to openrsync. With the switch, many of my backup and other rsync scripts broke, throwing errors and not finishing the sync. As of that last post, I had gotten things mostly working, but had to disable incremental snapshotting and still sometimes had failures that I had to deal with.

Mac: 15.4 rsync issues
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.
Rsync and dealing with “some files vanished” warning
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.
I looked for an option or simple solution to allow it to go on without complaining.

I have been using rsync for backup and other things for a long time. It has a link-dest option that allows doing incremental snapshots similar to Time Machine on Macs.
